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

What motherboard are you using?

From the information you have provided, it appears that you need the driver for USB 3.0 provided by VIA.

but i have two messages : driver not installed on universal serial bus(usb)controller and
driver not installed on unknown device.

Any help appreciated.

Answer:missing universal serial bus driver and unknown device

You missed one, download them all again and go one by one.
 
If you're able to extract the actual Driver files directly then just naviate to it from the Device Manager and update.
 
Things like these are tricky at times and require lots of manual work. Create one folder with all the drivers and start opening them one by one. Then move them over to another fold once you're finishied.
 
I like to download them and name them what they actually are. Makes it easier to track.

and when I connect it to usb port it apears like this >

When I go to Device Manager it apears like this >

And when I try to install the driver it shows me this >

What to do ? Any ideas ?

Answer:Unknown Device (Game Controller)

Use 7 driver if you can find one. If not, install the Vista driver in compatibility mode for Vista. Compatibility mode may cause it to install correct and recognize the device. Good luck.

If still no go, install by right clicking on that unknown device and choose update driver software. Browse my computer, let me pick, have disk, browse. Now find the .inf to the driver. Extract driver contents from rar or zip file beforehand if need be. Or if install file is .exe, let it extract to temporary folder first by running it. Then install with device manager as I said.

I had an "unknown device" show up in devices and printers a couple days ago. It was also listed in device manager and said it was a USB controller. Everything worked and I've not added any new hardware. I have 2 partitions both with Windows 7 and the error showed in both. I've found that others were having the same issue, some needed drivers, some said cables needed replaced. Before I got serious with the troubleshooting, I read up a little and found a forum that said you should shut down then disconnect the power cord, wait a couple minutes then power up. Sometimes the motherboard needs to reboot and the devices will be reloaded or reassigned as they should be. It worked for me, it was an easy fix to an annoying problem. Since so many people have posted about this I thought I'd share this. If it helps, great. If not, it didn't cost much time or any money.

Answer:Unknown device-USB controller not recognized

I can confirm this solution. I had the same problem and I turned off the computer, unplugged the power cable then plugged everything back in and restarted and the error message was gone. Finally!!! No more "Unknown USB Device" messages.

I'm really stuck, so I'd appreciate help if someone can give it.

I'm working on someone's computer. I should mention that I am doing this remotely, & I don't have another choice just now.

Due to a whole mess that with his computer, we needed to do a full destructive installation of windows. (XP Pro SP2)

Now, here's the problem. There were no USB devices listed in the device manager in windows after the new installation. There also aren't any unknown devices. There had been one, for audio, but I've fixed that.

The computer is older & the motherboard is a Microstar International MS-6738. I went to their site. i've run their live update multiple times but it just isn't finding anything missing regarding usb controllers and I did the 3 available updates for the motherboard. They didn't seem related, but i tried just in case. No luck, besides of course the audio working.

At this point I'm really at a loss. I feel like throwing the computer out the window, except I can't even reach it to do that! lol

Any ideas? Thanks for spending the time, for anyone who read this.
I did also run belarc advisor. If it would help, ask & i'll post it, as long as that's ok on this board.

I tried all available options like trying to update the driver manually but still i am unable to find any solutions. I would really appreciate your effort on this which will be very helpful. 

Answer:Network Controller G580 (20157) - Unknown Device

hi kalhemhtc,
 
Welcome to the Forums.
 
Can you try one of these drivers:
 
Windows 7 - G580 (model 2689, 20157)

Wireless LAN Driver (CyberTan, Liteon) for Microsoft Windows 7 (32-bit, 64-bit) - G580 (2689, 20157)
Intel Wireless LAN Driver for Microsoft Windows 7 (32-bit, 64-bit) - G580 (2689, 20157)

 
If the above drivers doesn't work, can you follow this guide on how to identify the network controller from its hardware ID.
 
 
Article:
G580 : Wireless adapter is missing message when connecting to WiFi
 
 
 
Let me know how it goes.
 
Regards

Hi there, I have a Lenovo Y510p with a frustrating problem. I've been having graphics performance problems and crashes for the last two weeks (suddenly unplayable FPS in diablo 3; hearthstone is barely responsive).  I was running windows 8.1, installed via the store upgrade, and thought maybe something had gotten corrupted. So I bought a student copy of windows 8.1 and tried doing a clean install of windows 8.1 followed by installation of the windows 8.1 drivers from lenovo's website.  same graphics problem So I went back to factory settings, doing the following steps: 1) Restore system using system restore one key recovery to original factory settings 2) Update all windows 8 files / drivers -> still have graphics problem3) Update to windows 8.1 via store4) Install windows 8.1 drivers from lenovo's website5) new problem I have have  Intel(R) HM86 LPC Controller - 8C49 showing as an unknown device in device manager.  Google searches suggest that this is part of the chipset, for which I have installed drivers.  I have not yet tested graphics performance until I resolve this issue. Any ideas what this is and, if it is part of the chipset, how do I successfully install the driver? Many thanks,Eric

Hello,

I just installed Vista over XP and no I get this error code/problem in device manager = other devices, Ethernet controller, unknown device. It has yellow error codes here. I know that the Ethernet card works because I can use it with ubuntu on my other drive.

When I attempt to get a connection or diagnose/repair I get, '' local area connection network cable unplugged ''. This exact configuration get me on line in 5 seconds with ubuntu Linux but not with windows vista. Everything with the new vista install works fine except the other devices in device manager. I cant get on line to download new drivers with that computer...any ideas?

Thanks.
 

Answer:other devices, ethernet controller, unknown device issue

Maybe this can Help.

Check the Device Manager for valid network card entry.

http://www.ezlan.net/Win7/net_dm.jpg

If there is No valid entry, delete any Bogus Entry, and re-install the card's Drivers.

Check the Network connections to make sure that you have a Network Connection Icon/Entry, and that the Properties of the Icon (right click on the Icon) are correctly configured with TCP/IPv4 protocol in the Network Connections Properties.

Make sure that No Firewall is preventing/blocking the Wireless components to get to the Network.

Hi there,As described in the header.I recently reinstalled my (recovery partition deleted long ago) Lenovo R60 9456-HTG. OS is Windows XP professional inc servicepack 3.At the same time I replaced the S-video controller of the laptop, since it was broken. I ordered a new one from Lenovo. To be clear, I replaced the part in which you insert the S-video plug, at the right side of the laptop, as seen from above.This new S-video controller doesn't seem to work, as no picture is being transferred to the television when I connect it. I am sure the problem is in the controller (or software), as the old S-video connector did work (crappy though, often no color). As soon as I start up my laptop now, the windows new hardware recognition tool tells me there is new hardware, but it is never able to update the drivers for it (not by automatic, internet, cd, manual searching, whatever). It then tells me the unknown PCI device found might not work properly. Using Sandra, Unknown device  or system tools (looking for yellor question marks) I cannot find any unknown  devices. Question is: How can I find out which PCI device Windows seems to be unable to find drivers for, after that, how do I find the driver, and last, is it possible that the PCI device unknown to Windows now is actually the new S-video controller (they changed the hardware maybe??? New driver needed for that???), or is that not a PCI device at all???  Best regards, Mathijs VosThe Netherl... Read more

Hi all.  please see attached dxdiag for my system specs.  note that this is a big desktop PC
 
 
this morning i noticed a device in the device manger which isn't working properly. Normally  if it's not a major issue, i'd consider that sort of thing a silly nitpick.
 
However, i'm currently experiencing a major problem (which shall have its own thread, later), and i need to start eliminating possible suspects
 
i tried to research this little issue, and i found some steps that seem really good for major discrete components. unfortunately usb host controller is a generic entity, i'm not honestly sure if it even corresponds to any particular usb headers or external ports.
 
I've already tried the basic steps of disabling/enabling it, un/reinstalling the device, restarting the computer, leaving it powered off for five minutes, etc
:
anyways, details:
 
the device is listed under the Universal Serial Bus controllers section of the manager, as "Unknown Device"
When i open up the properties menu, i see the following info:
Device type: USB controllers
Manufacturer: (Standard USB  Host Controller)
Location: Port_#0001.Hub_#0003
 
Device Status: Windows has stopped this device because it has reported problems (Code 43)
 
going by instructions i found elsewhere, i was trying to hunt through the details tab for the hardware ID. Unfortunately that option only reports the value USB\UNKNOWN

Heres the situation:

I installed a fresh copy of WIN2000 on my IBM Thinkpad A21m but I am having a problem setting up a device in Device Mangager. I have no idea what is going on.

When i reboot the laptop it prompts me that it has found a new piece of hardware and it wants me to install the driver for it. The problem is that I have no idea what device it is since all the devices that should be working are working - so i don't know what to do.

The clues that I have noticed that might help:

- the laptop takes a LOOOONG time to boot up (3 or 4 mins), and is sort of sluggish in operation (compared to how it ran when i bought it)
- my internet connection is super slow ( I have a DSL router that serves 3 computers incl. mine, the other two have XP and everythign runs smooth)
- the unknown device says it is located on the the "Microsoft ACPI-Compliant Embedded Controller"

Would any one know what Device this "Unknown Device" is??? I just need to know so i can install the driver so my system can run properly.

thanks,

Zach.

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.

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.

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.

Chris

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!!!

Answer:Unknown Device - Device Instance Path (ACPI\INT33BD\1)

Hi: I am pretty sure you need this driver.  The latest is for W8.1. This package provides the driver that enables the Intel SidebandFabric device. 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.

Answer:Satellie A300-1EC PSAG0E: unknown device in device manager

What OS have you installed?
Windows XP?

If yes, check if your Windows XP is up to date (install MS patches and hotfixes)
Also install all available drivers from the Toshiba driver page like:
Chip Set Utility, Storage Manager, etc? and if there is an newer BIOS version, then update it.

Hi,
My 7270 latitude touch screen stopped working shortly after first use (after win update worked again but for a short time).
All drivers are up to date.
In device manager a USB device shows as unknown (yellow warning triangle), otherwise there are no indications to the source of the problem.  There is no other touch screen device showing in device manager. 
How do I perminently solve this?
Thanks

Any suggestions?

Answer:Portege R700 (PT311E) - Unknown device in device manager on XP

Hey,

In my opinion this device has something to do with chipset and therefore you have to install the Intel chipset driver. You can download all drivers on official Toshiba website:
http://eu.computers.toshiba-europe.com

Check also the exact vendor and device ID in device manager to identify this device. The PCI database website can help you to do this:

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

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......

Vista Home Premium, all other Toshiba SW installed (value pack, intel, BIOS 1.9, etc... - maybe BIOS did this?!)

Thanks in advance!!!

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

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?

Well it might be a good idea to look at the following tutorial:

Use the link in Step 7

Also I tend to find this tool useful:

Right click on each result in the list for more options.

Edit: On my machine a similarly named device appears to be a webcam.

In the list USB Composite Device doesn't mean much but matching the ID seems to indicate that it's the webcam.

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 decided to do another reformat on my hard drive. This time, I ignored the optional updates. 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. Could it be the Intel chipset driver that the optional update is pushing? I'm not sure. I went back to Device Manager, th... Read more

Hi.

It WinXP Pro + SP 3.
In Device Manager display, as an unknown device. Try all drivers, who were on a disk along with the laptop, nothing helps. Give the solution!

Answer:Re: Satellite 5200-701: Unknown device in the device manager.

Hi,

who should give you THE SOLUTION? I mean, you tried all drivers and nothing did installed... So, does your machine run properly? Does some device not work like it should?

Please check this firstly before installing all drivers without any success. Try to guess which device it could be, so then we can search for some solution.
A good beginning would be to check the device in the device manager and write some of the information which is contained in the Properties window of the device.
Please post the details which are in the properties of the device, maybe someone here in the forum can find out which device won?t work.

I assume also that the SP3 makes some problems, so another good option would be to deinstall the SP3 and go back to SP2.
