Preferred Solution: Unknown USB Device(Device Descripter Request Failed)

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.
The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.
The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.
Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.
I've tried:
uninstalling the device and rebooting
installing the latest updated chipset drivers from the dell website
windows updates
pretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

Any other ideas?
Thanks

Answer:XPS 15 9550 Bluetooth stopped working (Unknown USB device - device descriptor request failed)

So in desperation I just went into BIOS settings to see if there are any BT settings that may have become disabled. I didn't see any, and I didn't change any other settings.
After rebooting, BT and my mouse is now working again.
Something seems to be really flaky here, but hopefully this will help others with the same issue.

Answer:Unknown USB device (Device Descriptor Request Failed)

hi kmugal,
 
Welcome to the Lenovo Forums
 
The issue that your having is most likely the one discussed in this article.
 
If you have tried the USB 3.0 (x2) and USB 2.0 (x1) ports with the same issue, consider the following:
1. Unplug all USB peripherals connected on the machine
2. Run Windows Update to get the latest patch and bug fixes (reboot if necessary) and try the USB devices.
 
If the problem remains, consider going back to Windows 8 by doing a Refresh or Reset to isolate any issues on the OS level.
 
 
Regards

Fresh install of Windows 10 and the last driver I need to sort out is the above.

I believe it is my powered USB 3 hub to which I plug in my keyboard and mouse. Technically it is working but I don't like seeing yellow triangles on devices.

So are there any fixes?

Answer:Unknown USB Device (device descriptor request failed)

If it's a generic USB 2.0 Powered Hub then technically there's should be no drivers needed by Windows, if it's a USB 3.0 Hub then I'm unsure (since I don't own any USB 3.0 Hubs).

Might be a Windows bug, basically Windows can't find the description information to display the Hub's name in the Device Manager example: Generic USB Hub, Root Hub Device, etc....

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".

My computer keeps telling me Unknown USB Device (Device Descriptor Request Failed), so I looked up how to fix it and they told me to uninstall it then scan for hardware changes and it will reappear working properly. Only it did not come back working properly, it came back the same. I am also 98% sure that this "unknown USB device" is my built-in webcam that has never once worked. So if someone wants to help me out and allow me to use my webcam that would be great!

Some of my ports do not work all the time, I cannot identify a specific moment. Inside the Device Manager, Universal Serial Bus controllers, I get 1, 2 or more "Unknown USB Device ( Device Descriptior Request Failed )", sometimes more sometimes less.

Motherboard: AsROCK H77 Pro4/MVP
Windows 10 all available updates downloaded and installed as of today, and everyday. The problem appeared on Win 8 or 7, not sure when. So it's not necessarily Windows 10 specific. I ported it to 10.
Here is what they look like:

Bios is up to date. Chipset drivers updated, various solution tried from googling, I even managed to make all USB ports stop working testing some of these solutions, I had to restore windows from a ghost image I had.

It's like these USB ports remain suspended sometimes.

Any advice on what to try? The most annoying part is that from the frontal USB ports some stop working randomly too.

Thank you

I know that a similar question has been asked before but, not with the last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

Answer:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

When I try connecting the flash drive nothing happens, however, when I try connecting the USB mouse it says Unknown USB device (Device Descriptor Request Failed) in the device manager, windows error message "USB Device not recognized" also pops up in the bottom right corner. When I try connecting either of them (the mouse of the flash drive) to the 3rd USB port (the usb 2.0 port) they both work perfectly fine without any errors at all. I would like to know what may have caused that error and if there is any solution at all. Thanks in advance, Mersif.

When my girlfriend connects external USB device to any of the USB ports on Windows 10 Home she gets message:
USB Device Not Recognized.
She can not charge USB device via USB port.
I went to device manager and under USB Controllers I see following:
Unknown USB Device ( Device Descriptor Request Failed).
I tried some tricks I googled for this message but none of them returned result.
She didn't get any of the drivers with this device which needs to charge.
What should I do to be able to charge this device via USB?

Answer:USB Device Not Recognized Device Descriptor Request Failed

Try the device on a different USB port. This will figure out if problem is caused by a broken port.
Connect the device to another PC. This will figure out if the external device has problem.

Open Device Manager and expand category Universal Serial Bus Controllers and locate the USB device which is not being recognized by Windows.

Right-click on the device and select Uninstall from the context menu.

After finishing the uninstallation, restart your PC then Windows will reinstall the device automatically.

The problem can be caused by faulty USB driver. In this case, updating driver would fix the problem.

Obtaining Hardware ID's to help Identify Hardware
- Go to Start and type in "devmgmt.msc" (without the quotes) and press Enter
- Expand the "Unknown USB Device" category by clicking on the + sign to the left of it
- Right click on the "Unknown device" (if there's more than one, do this for all of them) and select Properties.
- Then select the Details tab.
- In the dropdown box, select "Hardware IDs" - and match the info to one of the following descriptions:

I have an external Bluray/DVD drive (ODP1201=S3-B) that works perfectly on Windows 7 but is not recognised by my new laptop which has Windows 8.1 64 bit. Can anybody explain why this is and what I do to get pass it, or is this a problem with Windows 8.1?

The device is listed in Win 7 as "hp bd rom bc 5501h", and the driver is 6.1.7601.17514

I have now tried various USB devices; I have connected a USB 2.0 External Hard Drive and a USB 2.0 Canon Camera both of which work OK, I have also connected a Seagate 1T external drive which is USB 3.0 an that was OK as well (the ports are all USB 3.0 on the laptop hence the reference to the which USB type)

The error message is as follows: "USB Device Not Recognised", When I go in to Device Manager I find two USB error listings, Unknown USB Devise (Device Descriptor Request failed) & Unknown USB Devise (Port Reset Failed)

I have been advised that this error can arise when a drive doesn't receive enough power from the system. The device does have two USB connectors, I have tried using both of them. The power cable going to the powered USB on the laptop and the data going to the adjacent USB (there are a pair of USB sockets on either side of the laptop, the right hand side having the only powered socket).

Answer:Unknown USB Device - A request for the USB device descript

I'm too of opinion that it's a power issue. Laptops are not known to have much power thru USB ports, not even some desktops for that matter. Possible solutions: If that laptop has USB3 port you can try it in there, it gives more power and is compatible with USB2. Another one is to ad external power to the drive. One of the USB connectors on the twin cable has only two connection tabs and is for extra power to device. That one can be connected to universal USB charger for phones etc. That's how I solved a problem with a HDD in external enclosure.

Hi,
I sporadically gets the "USB Device Not Recognized Device Descriptor Request Failed"; however, while I have 6 USB devices connected, none of them seem to be the cause of the error. When I use devmgmt.msc to get the Hardware Ids, the value is simply "USB\DEVICE_DESCRIPTOR_FAILURE". I use TARGET software to control two joysticks and a rudder. (Besides these three USB devices I have a keyboard, a mouse and a TrackIR 5). In some instances everything works even though I got the error but in others instances none of the joysticks are working as expected. Sometimes restarting the computer helps or uninstalling the "mystic" USB device, however the problem always reappear and I would really like to get rid of it permanently.
Anyone got some idea what could be causing this?
I have updated all drivers but it did not help.
Thanks,
Klaus

hello guys in my device manager there is a yellow triangle on a usb device driver saying : a request for device descriptor request failed first i thought maybe 1 of my us ports not working but when i tested all ports are working even card reader but the error is still there i updated drivers (chipset - etc) but it didnt help so i want to know how to get rid of that error and what is the problem with my laptop?
note: sometimes when i trun on my laptop that error is gone mysteriously and most of the times its showing up
note: i recently changed my wireless adapter tho the orginial adapter was a bt/wifi combo but the new one is just a wifi adapter and i have an ssd installed instead of dvd optical drive and both are working well
note: things i already tried: disabling fast boot-updating generic usb drivers-taking out battery for 5 minutes-updating drivers

Answer:a request for device descriptor request failed

i recently changed my wireless adapter



Is this a USB adapter? Does the error go away if the adapter is removed? With the yellow flag in Device Manager, right click it and Uninstall it. Remove the USB Device from the computer end and Restart your computer. When the computer comes back up, plug the USB device into different USB port of the computer.

Hey, I have some errors in device manager like port reset failed and device descriptor request failed.Long striy short: I have already tried all the standard answers several times. I dont know wich device is/was the one who caused the error. It coud be mine (already contected everything I have) or of some other person. My probem is not the "problem"... What really annoys me is windows keeping refreshing the device manager and with that causing my pc to freeze for a second randomly. I have unsinstalled the device, plugged the pc off power for minutes, tried to remove with usbdview and usboblivion and all the stuff with energy options! The thing is that an error loke that seems to not be a big thing, but I cant use my PC anymore. I need windows to stop trying to reset the usb port or whatever it does, just forget about the error/device. Has anyone an idea how to get rid o this? Thank you and hope the answers will help other too!

Answer:Device Descriptor Request failed

Hi timniko. Welcome to the TenForums @timniko

Can I ask when did this problem start? Had you added a device?

Have you tried resetting your BIOS? (Before you do please ensure you document or know current customizations?)

Have you check manufacture's site for a newer BIOS? Not recommending you update BIOS but it would be nice to know if they have a newer version. Updating BIOS has its own risks which can result in a "Bricked" machine.

I assume this problem happens with all external USB devices removed, correct?

Is it possible to get Hardware id's from device manager for problematic devices?

Hello
I have a USB device (X.Vision PCDVB-3100)
It work properly in Windows 8 and Windows 8.1
But now in Windows 10 when I connect it to USB port, The Windows give me this error:

?Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.?



How I can solve this problem?

Answer:A request for the USB device descriptor failed

Probably the USB port cannot provide enough power to the device, so Windows cannot properly identify it. Try connecting it to a different USB port. If problem persist, the only solution is to use a powered USB hub that will provide the power necessary. Also some devices have problem working on a USB 3.0 port (blue), try using a USB 2.0 port (black).

Let me start out by saying that I've googled the shit out of this problem, tried several things, and nothing worked.

I have a D-Link USB 2.0 Hub that I got about a week ago. It's been working awesome up until recently. It's a plug and play device, however windows is failing to recognize it, and thus making everything I have plugged into it unusable.

In the 'Device Status' box it says:

Code:

(Code 43)A request for the USB device descriptor failed.

And in the 'Events' tab, there's a few listed, I'm not sure if they are much help:

I have a flash drive that I previously used in public computer lab (where many viruses linger) the other day to do my work. As I got home, the flash drive isn't working anymore, saying "USB Device not Recognized". I also noticed that it really took me a while to finally, safely remove it from the computer lab's PC. So I actually wonder if it actually removed my flash drive properly.

On Device Manager, it says "Unknown USB Device (Device Descriptor Request Failed)".
On the Properties, the device status says "Windows has stopped this device because it has reported problems. (Code 43) -- A request for the USB device descriptor failed."

My flash drive is a Kingston Flash Drive DataTraveler (DT100) 16GB, and my PC is running on Windows 8.1.

Things I have tried:
- Shut down my PC, unplugged power and removed battery, waited for a while, booted my PC and try plugging in again.
- On Device Manager, uninstalled it and scanned for hardware changes, it still returns as "Unknown USB Device".
- On Device Manager, I clicked "Update Driver Software..." and it returns me a message saying "The best driver software for your device is already installed".
- Unfortunately, when I visited Kingston's website to check if there is driver for this specific flash drive, there isn't any... "There are no downloads or drivers available for this product".
- Used Windows 8's Troubleshooting tool. It only detected my problem, but was un... Read more

Answer:USB not recognized (Device Descriptor Request Failed)

if you have tried on other systems using different OS then the error is normally because of issues with the item not the PC , it might be 'confused' or have corrupted data or be faulty.

If you have the data still stored elsewhere...then you may be able to reset the flash drive and see if it recognises it then.

I'm not sure if there is a reset switch anywhere on that stick.

Hi all,

(Unknown USB Device - A request for the USB device descriptor failed)

Massive problem I have encountered since buying a new laptop pre-installed with Windows 8.1

I have 3 external USB storage devices - 1x Corsair "Slider" 64GB, 1x HiTachi Touro 750GB, & 1x HiTachi 4TB external drive. ALL drives are coming up with the same error message and are not being recognized by Windows 8.1

The strange thing is, I also have another 2 PCs - one with Win7 and one with WinXP and the drives work without issue.

I've spent the last 4 days scouring the net looking for answers, and thus I am here hoping someone can shed some light as to why ALL of these drives do not work on this new laptop pre-installed with Windows 8.1?

Even stranger still is I have other thumb drives, a cheap Transcend 32GB (which is USB3.0) and a few cheapo (USB2.0) drives of various sizes by Strontium, Lexar and so on which work perfectly.

But the one that has me o.O is an expensive 64GB thumb drive called the Mach Extreme which also works perfectly with this laptop???

So all up 2x HiTachi drives & 1x Corsair thumb drive are not working and its driving me bonkers!

If no drives worked at all, then I would be seeking the manufacturer for maybe a faulty component. Dodgy USB ports, or maybe a motherboard problem. But having a handfull of drives, of various makes, sizes and both USB3.0 - 2.0 fully working leaves me scratching the old chrome dome as to what could be the issue

Answer:A request for the USB device descriptor failed. (error43)

You can mark this thread as SOLVED!

Okay here's the fix that worked for me, maybe it will work for you.

I've always updated drivers, WinXP, Win7 and so on, the same way - download the driver, go into device manager and select browse, then point windows to the downloaded driver to update the necessary files. Its always worked that way for me for as long as I can remember.

Not so it appears with windows 8 - for some strang reason.

For me I had to update to the latest Intel Chipset Drivers, but instead of the tried and trusted methos above, you simply hit the setup.exe and let windows 8 do its thing. Believe it or not, but this fixed the issue.

Yes I had already updatd to the latest Intel Chipset Drivers using the device manager method, and yes windows "did" update ...someting??? But the USB devices were still showing the Unknown USB Device error. But using the setup.exe fixed the everything and all my USB devices are now working perfectly with Windows 8.

How, why, who knows, but I hope this works for others with the same problem.

Hey guys... I am about ready to pull what hair I have left out of my head. Here is my setup:

-MSI X99A Pro Carbon motherboard
-Intel Core i7 6800K prcessor w/Cooler Master Hyper Evo 212 cooler
-32 gigs of DDR 4 Quad Channel ram
-Windows 10 Pro

Hi all,

I have a problem with my Lenovo B50-70 Laptop. It has 2x USB 3.0 and 1x USB 2.0 ports.

It started when I removed a USB mouse from the USB 2.0 port. I had a message flash up saying
Windows has stopped this device because it has reported problems. (Code 43)

A request for the USB device descriptor failed.
If I go to Device Manager and 'Uninstall' the device, then plug the mouse back in and 'Scan for Hardware changes' it works. However whenever I unplug it I get the same error. I've tried doing them same thing and plugin in other devices, (my phone, a memory stick) and The error comes back. If nothing is in the port and I scan for hardware changes I get that message again.

Any ideas how to fix? It is almost as if the machine doesn't detect the mouse is unplugged and thinks it's gone wrong. The USB 3 ports are fine.

I've tried...
Checking for Driver/bios updates.
Cleaning the port.
Uninstalling all USB Drivers and reinstalling

Hello Ladies & Gents.

I would like to ask for your assistance on this slightly annoying problem.

I have 1 pair of Razer Megalodon USB headphones, on the start up of Windows 8.1 these headphones are not detected correctly. The only proof I have of this is in the device manager displays:

Universal Serial Bus Controllers -
Unknown USB Device (Device Descriptor Request Failed).

(Please see attached screenshots)

Once the device is disconnected and reconnected device manager then displays:

Universal Serial Bus Controllers -
USB Composite Device

The device then shows in "Audio inputs and outputs"

Cheers,

Mr Collective

Answer:Razer Megalodon - (Device Descriptor Request Failed)

Razer is well known for BSOD drivers and problems, otherwise. (And taking very old drivers, changing nothing at all, giving it a new date and then claiming "Compatible!" with new OS.)

Perhaps give a shot with uninstalling their software, rebooting, the re-installing.

Make sure using the latest.

When all is said and done, you might just have to live with it.

Can't hurt to make sure chipset drivers are up to date. If Intel chipset, search their driver site for "Inf"

I'm attempting to help my daughter fix her USB issue, so the information I have about the computer is minimal at this point. The computer is and HP Pavilion a6710t Desktop PC. It has a Foxconn motherboard. Here's the story, She's been using this computer for a couple of years, was running Window Vista. One day her wireless mouse and keyboard quit working. I gave her a usb mouse to try to no avail. The message when we plug any USB device that previously worked on her computer is 'Unknown sub device, device descriptor request failed'. After doing much research online and attempting a multitude of fixes from online sources I had the bright idea (being the computer genius that I am (NOT!)) to update her Operating system to either Windows 7 or Windows 8. She chose Windows 8. Here I'm thinking if I wipe the hard drive, do a clean install of Windows 8, the problem would be fixed. Boy was I wrong, still no USB ports are working. Makes no sense to me unless it's the hardware itself. Any suggestions? Ideas?
 

Answer:USB ports inoperable, error says, device descriptor request failed.

Based on what you have tried, it does seem to be a hardware error. One more thing to try is check the CMOS battery's voltage. It's usually a CR2032 rated at 3 Volt. Carefully remove it after unplugging the PC from the socket outlet, and check the voltage with a digital multimeter.

I have a Kingston HyperX 64Gb memory stick, formatted FAT32, that Win8.1 doesn't recognize. I plug in the memory stick to any USB 3 or 2 port on a Dell XPS15-9530 and Win8.1 appears to recognize it, assigns a drive letter then immediately says "unknown

BIOS is up to date. All updates to Win8.1 have been applied. Kingston have no drivers for this device. I've tried setting USB power setting "Selective Suspend Setting, both battery and plugged in, to disabled and it makes no difference. I've removed
the device in "devices and printers" and then rescanned in device manager with no success. Is there anything further I can do?

Hello everyone,
i hope you can help me sorting out this issue that is causing me a hard headache at the moment.

I've bought this new Lenovo Z50-70 laptop with windows 8.1 preinstalled on it. Fresh new.

I'm trying to connect via usb a guitar audio interface (Line6 POD HD500) so i installed the drivers via the .exe setup file i downloaded from Line6's site.
The device worked fine on my previous HP pavilion with windows 7.

Now when i completed the installation, i connected it and i had this error:Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.
I used slimdrivers to update all the other drivers, in case it was a conflict causing the error.
I checked via command prompt with command "pnputil -e" and i saw a driver from the vendor of the device listed, so it is installed correctly i think.
I tried all USB ports i have, 3.0 and 2.0 on one side of laptop and 2.0 on other side.

When on device manager, if i click update drivers and choose the "let me pick from a list of device drivers.." i don't see the company name of the device.

i saw that another guy posted a really similar problem on SevenForum and he figured out how to force windows to use the drivers but he didn't post the solution.. Here is the post: Can't get Windows 7 x64 to use the drivers I've installed repeatedly Solved - Windows 7 Help Forums

Answer:Lenovo Solution Center Shows Unknown Device But Device Manager Doesn't

Hi,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to inform that it is a false indication from Lenovo solution center. Since Windows doesn?t detect any missing device drivers within the device manager, there is no driver that is missing.
If the warning keeps popping up, change the reminder settings to ?never?. Probably, you have to wait for an LSC update in which the bug would be fixed.
 
Refer here for further information regarding the issue.
 
Hope it helped!

Hallo,

I have installed Vista on my Satellite A100-771. I have also installed all the drivers downloaded from the Toshiba Support site.
But when Vista starts, one message come out always ----- new hardware founded. I really don't know which hardware it is.

There is a unknown Device in device manager, and windows cannot find the driver for this device online.

Can anyone help me?
Thanks a lot!

Answer:Vista on Satellite A100 - Unknown device listed in device manager

Hi there,

may I ask you which drivers you?ve downloaded? And regarding the new founded hardware: Did you checked your device manager for that device?
What is standing there as the non-installed device? Mass-storage or multimedia? Please be more precisely with your explanation and don?t forget the drivers to list.


Thx

I can no longer use the mic that came with my Xbox 360 wired controller on my Windows 10 PC after I upgraded to the Creators Update a few days ago. In the Device Manager it is listed as 'Unknown device' and if I try to 'Upgrade Drivers' then I get this error message: "XBOX 360 Headset Device. An error occurred during the installation of the device. The driver installation file for this device is missing a necessary entry. Contact your hardware vendor". Anyone have any idea how I can get it working again? I can't find the driver for this thing anywhere! I used it for Cortana searches as well as communication in Overwatch.

Answer:Satellite A100-926: unknown device bus pci7; device:6; function: 3

Did you reinstall the operating system on your notebook?

Usually the notebook is delivered the Toshiba image and there should be unknown devices in the device manager?

In the forum some guys have placed the link to the very useful Toshiba document.
It described how to identify the unknown devices.
http://support.toshiba-tro.de/kb0/TSB57014E000QR01.htm

Maybe it will help you to find out what device it is.
Then you can download the right driver from the Toshiba page?

Intel Sideband Fabric Device Driver is a bridge tothe Intel Dynamic Platform and Thermal Framework. This package isprovided for supported notebook models that are running a supported operating system. File name: sp65474.exe I don't know if not having that driver installed is related to the black screen issue.

Hello there!

I would be very grateful for any help/hints if somebody has an idea what to do....

My gf has the above mentioned laptop (w/o preinstalled OS) and we can not get the display adapter to work properly - situation is as follows

1) mobile intel 4 series express chipset family and an unknown device with a question mark in device manager
2) both are on the same PCI BUS 0, device 2?
3) intel is not working because it has no free resources (should I delete the unknown device?) to work with
4) HW ID for the unknown device is pci ven_8086&dev_2A43 and for intel is pci ven_8086&dev_2A42 (so basically the same, right?)
5) last, but not least, if I go to Desktop-personalize-advanced (first of all no 1280*800 resolution) i see under adapter type: . Exactly, nothing... under properties, this appears: non plug and play device, Super VGA and under driver, I see just the status and option to Stop, Disable, Automatic, Demand.... the device on startup... .If i disable it, the display just does not light up when the laptop is turned on....
Any ideas? I am going insaneeeeee......

p.s. maybe SP1 that I am installing now will help?!

Answer:Satellite L300 PSLBGE - Unknown device in device manager

Hi

Wait a moment: I have checked Vendor ID and Device ID on www.pcidatabase.com and this device is the Intel graphic card. So I think this is the reason why you can?t change the screen resolution.

I assume that you have forgotten to install the display driver. Check the Toshiba website because there you can download the driver:
http://eu.computers.toshiba-europe.com => Support & Downloads => Download Drivers

After this you shouldn?t have any exclamation marks anymore.

You can install SP1 for Vista but this will not solve the problem with the missing display driver. But you should install it because it contains a lot of security updates they are important. Furthermore I would recommend to install SP2 for Vista.

Bye

Dear All,

I bought a Satellite L30-PS33 with Vista but due to driver issues with my existing peripherical equipments, I decides to change from Vista to XP.
I have a problem with internal HUB usb, even if the installation is OK with windows XP generic drivers when I plug an USB devise, I have the message: Unknow device.

Can you give a link to find the good drivers I have to use in my computer?
It's very difficult to use a computer without any USB equipment?

Thank you and I hope you have any solution for me.

Best regards.

Answer:Satellite L30-SL33 : Unknown device after pluging external device to USB

There are no USB drivers for any Windows operating system.
Fact is that USB driver are a part of the Windows system and you will not find any 3rd party drivers for a USB port.

In your case I would recommend updating the BIOS and to update the Win XP to the latest state. All XP patches and updates should be installed!!!

Hi everybody.

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.

Thanks.
 

Answer:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

Hello,
I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 header or the motherboard shipped that way and I inadvertently made matters worse. Anyway, that header on the motherboard is without a doubt unusable.
Since I don't really need the USB 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 boots and I plug a device into the front ports of the case, Windows detects the front USB ports as "Unknown Device" within Device Manager yet says the driver is successfully installed. I've already downloaded the most current Intel chipset drivers for my motherboard, deleted and reinstalled all USB drivers, and all rear USB connections are working perfectly fine - it's just the two front ports that are connected from the case to the USB 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 headers on the motherboard, and I've tried plugging in several devices to the front USB ports, and this problem still persists.
I've ensured the connection inside the case is solid, yet I cannot get Windows to recognize the front USB ports.  However, I have confirmed that power is being sent to the front ports because it charges my phone when I connect it to the front USB ports via m... Read more

I have a Toshiba laptop, model L505-ES5018. I had Windows 7 Home Premium 64 bit installed on here, but decided to reformat my hard drive using Windows 7 Ultimate 64 bit. After the reformat was finished, I ran Windows Update and it found several items to download and install for me. I noticed that it also found optional items to download and install for me, so after all the important updates installed, I ran the optional updates. After all of this installed, I checked Device Manager to see if there were any errors and I found nothing. I assumed everything was fine. I decided to check Devices and Printers and under my laptop icon, there was a yellow icon with an exclamation point on it. I decided to run the troubleshooting option when I right-clicked the icon....it gave me a solution to download a Toshiba password utility program, so I did that and nothing happened, even after restart. Same icon appeared. When I clicked on the icon a second time, I noticed that the model of my computer at the bottom of this window, changed from L505 to TIAS. I have no idea what this is.

I checked Devices and Printers again, the same icon appeared but the model of my computer said L505, like it should. There is something in the optional updates that is changing this.
