Front USB Ports not Working - "Unknown Device" in Device Manager

Question: Front USB Ports not Working - "Unknown Device" in Device Manager

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 micro USB connection.  As a result, I'm inclined to think this is a driver issue rather than a hardware issue.  Any ideas?

Do you happen to have a spare machine that you can test the adapter with?  Just as a precaution in case the adapter is faulty.

Hi, I am using T410 for a couple of months. its camera was working but it has suddenly stoppped working now. in the Win7 device manager it appears as unknown device and in details: -"Windows has stopped this device because it has reported problems. (Code 43)"I have tried re-installing drivers and rebooting machine etc but no help. Please suggest how to fix this. Also tried reinstaling ehci controller device but no luck. Thanks,manu

Answer:Webcam not working on T410, detected as unknown device in Win7 device manager

hey manugautam000,welcome to the forums, disable to camera from device manager and remove the current driver installed to it.reboot your unit, re-enable the camera. windows should then install its own generic drivers.test your camera with the generic drivers.later on, head to http://support.lenovo.com , download the latest camera driver for your unit. set your unit to diagnostic mode via msconfig and then install.

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

Hello everyone,I has a problem: All usb ports not working on my Thinkpad T440p. I tried to use different usb devices (keyboard, headphones, mouse), integrated camera also doesn't work. Windows tries to install driver for device, but then says "Driver not found". Device manager displays two devices with name "Unknown device".Both of them has Hardware id: USB\VID_8087&PID_8000&REV_0004And locations: Port_#0001.Hub_#0001 and Port_#0001.Hub_#0002I was tried to reinstall all lenovo drivers, also followed every suitable troubleshoting instruction at microsoft answers and nothing helps me.

Answer:T440p - Unknown device - USB ports not working

I was found solution. Just wrong path to location where drivers must be found. In Device Manager right click the device or the unknown device to update drivers.Point to ?C:\Windows\winsxs? when it asks for the driver location.That's all.

Computer: Laptop, Samsung r780.
OS: Windows 7 64-Bit

I have a wireless mouse and USB headphones that worked fine up until a few days ago when they both periodically stopped functioning. 2 days ago they stopped functioning entirely. They work on other computers and nothing connecting to a USB port works with this computer. There is an Unknown Device listed under Universal Serial Bus Controllers.

Here's what I've tried:
Did a system restore
Reinstalled all 64-Bit drivers available for my system on the Samsung drivers page
Right-clicked and uninstalled all drivers from Device Manager, then restarted computer
Took laptop battery out, waited 15 minutes, then put it in and started computer
Downloaded USBDeview and uninstalled all drivers listed (curiously, the Unknown Device is listed as not connected and not safe to unplug), then restarted computer
Ran Windows 7 Upgrade Advisor with mouse and headphones plugged in. No problems found.

Does anyone know what else could be done?

Thank you for your time

EDIT - The mouse lights up when its plugged in, even though Windows doesn't acknowledge it and moving and clicking doesn't work.

Answer:Unknown Device, no USB ports working, tried everything I could find online

In Device Manager click on View at the top. In the dropdown show hidden devices then uninstall all listed usb items.

Cleaned registry using Registry Mechanic

Thank you for your time.
 

Answer:Unknown Device, no USB ports working, tried everything I could find online

All registry cleaners do damage. Registry Mechanic is among the worse and may have made the problem worse. All registry cleaners do is delete anything they do not understand. That means that anything related to a device that is not on the system may well have been deleted, too, making it impossible to ever install that device again.

Restore the registry, or use System Restore to get an undamaged registry back.

Are you sure there are no physical problems with the USB ports? Any electrical storms lately?

Windows Update released updated USB drivers for both Microsoft and third-parties. If your USB ports are functional, there should be drivers installed automatically if you install all the updates. If not, the problem with the ports may be physical. Also make sure that the BIOS has the correct date and that USB is enabled there (if such a setting exists). If the date is wrong, replace the battery.

I am on a Toshiba A15-S127 which was working running XP SP3 until a couple of hours ago. I was on it, and all of a sudden the USB ports just stopped working. I dont know if this is relevant, but i did not have any problem with the USBs before my laptop started doing random "chkdsk" at startup. I need to get this cleared up soon as I use an external harddrive and have precious files on there that i may need to access.

Please Help!

Thanks!
 

Answer:USB ports not working, device manager says they are fine

Just thought I'd add this in: the external drive works at startup, the light turns on an it appears to be on and working but then once i am past the windows screen, the light turns off and once again nothing from the USB ports is recognized.

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!
 
Best regards,
Mithun.

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

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 there,I performed clean Windows 7 installation on my Lenovo ThinkPad Edge E545 laptop, I installed all the drivers and Windows updates, however I still have one unknown device in Windows Device Manager that I can't get to work properly. I do not know what the device is and Windows troubleshoot doesn't help at all. I did some googling and checked your Lenovo support and found out that this might be missing Power Management driver but I have installed it and the issue persits. When I go to device's Details tab it lists two Hardware Ids: 1) ACPI\SMB0001, 2)*SMB0001 (screenshot provided).Unknown deviceI have also tried to install AMD SMBUS driver and many others (Synaptics driver) and in the end I got rid of all unkown devices from the Device Manager except this last one. Could you please advise on which driver I might have missed or what steps need to be taken to solve this issue? Thank you very much in advance,Michal

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

One more yellow ? to go.  Thanks to the good advice rampant on this forum, I was able to figure out how to install the other drivers I needed.   This last one is messing with my mind tho.  It's unfair for a problem to not even have a name, doncha think?   About all I can fathom about this 'Unknown device' is its location:  'on Microsoft ACPI-Compliant Embedded Controller'. I tried the driver for 'Embedded Controller' and when I double click, it takes over the computer and tells me not to shut it down and begins installing 49 fixes.  When I did it, the program got to the 21st fix, and that was as far as it would go.  I shut down the computer after about 20 minutes.  It did not remove the 'Unknown device' remark in Device Manager. What's a poor boy to do? Also, Windows is taking forever to load. This was not the case yesterday.  Thanks for all your help. 50GreenDodge in Phoenix

Answer:What is my 'Unknown device' in Device Manager? - ThinkPad T40 2374-75U

Hello, Have you tried installing the Lenovo System Update software to see if that detects any missing device drivers and offers to install it for you? The latest versions for your ThinkPad T40 Model 2374-75U can be found here on Lenovo's web site. If if that does not work, you could try going back into the Device Manager (filename: DEVMGMT.MSC), selecting the Unknown Device to view its properties and then go to the Details tab, where you should see several values listed in the property sheet for things like "Device Description", "Hardware IDs",  "Compatible IDs" and so forth.  Try using these as search terms in your favorite search engine to see if doing so leads you to a more detailed description of the device, including a manufacturer, brand, model or part number. Once you have that information, it may be easier to find the appropriate device driver for the unrecognized hardware. Regards, Aryeh Goretsky

Hi there,I recently installed Win7 Home Premium on my Dell Inspiron 1525 which previously ran WinVista Home Premium (both are 32-bit.)However, in Device Manager, there are two devices named as; Base System Device, each with an (!) mark for them. When I dig deeper to see what these devices are, I get the following name for each of them;1) PCI, bus 2, device 9, function 3 and,2) PCI, bus 2, device 9, function 4When I then look at the Physical Object's Name, I get this;1) Device\NTPNP_PCI0024 and, 2) Device\NTPNP_PCI0023I'm not really sure what is going on! I tried using Win Updates to find the drivers, but it cannot find anything. I have a feeling that they may be devices for the integrated webcam and the card reader; however, I know I installed a driver for the card reader, so I am not sure what the other device is for... :sAny help would be greatly appreciated, Thanks.J

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.

hi ktmcmo,
 
As per the Windows 8.1 Upgrade Guide by Lenovo, certain components and their functions might be affected after upgrading the unit to Windows 8.1 (this includes the USB Port).
 
Just to verify, have you tested both the USB 2.0/3.0 ports using any usb devices (flashdrive, mouse, etc.)? If you see that one port is not functioning, you can try to:
1. uninstall all USB Root Hubs under USBView or Device Manager.
2. Install the Intel Chipset Update Utility.
 
Intel chipset Driver 
     Version: 9.5.10.1658
     Windows 8.1 (64-bit)
 
3. Reboot the PC and observe.

First, That was solved by uninstalling and rebooting, did not appear anymore. But as I said in the previous topic, that solution does not leave me entirely peaceful.
Since when searching for information on the issue, some say it may be a virus. But also by the HWMonitor. I prefer it was caused by HWMonitor instead of a virus.

Can give me a hand to remove my doubts about whether it was caused by a virus or not.

2.) Run the scan.

3.) When the scan finishes, save the results per the screenshot below. Then upload the log here.

I have this exact same problem-it occurred all of the sudden one morning when I tried to log on.I believe the "Unknown Device" (one of the "System Devices" in the Device Manager) is the ATK0101 ACPI Utility and uses a driver called A0101X32.sys which seems to be nowhere on my computer (I have no idea where it went or why it vanished). However, I cannot manage to find this driver on the website and download/install it, and what's more, when I try to do so, the "Update Driver" dialog boxes informs me that the file I must find is one with the extension "*.inf" which doesn't make any sense whatsoever.Has an answer to this problem been found?

First of all let me tell that I know very little about computers so I hope my terminology is correct. I bought my daughter a new computer 11 months ago and she is now having problems with the memory card reader. This is a Compaq Presario SR1603WM that came with CD-RW/DVD combo drive, 9 in 1 memory card reader USB interface,two USB external ports, windows xp, microsoft service pack 2. (anything else you need to know, just ask). Several months ago had a trojan virus while using Norton antivirus and am now using AVG and last scan showed no virus. The memory card reader has been used since then with no problems. A few weeks ago put the memory card in and it showed nothing. Looked under "my computer" and the only device with removable storage showing was CD/DVD. I tried troubleshooting on HP website and so far none of them have worked, including physically disconnecting the reader and reconnecting, reinstalling drivers and software, ensuring all devices are enabled, and compaq recovery (nondestructive).  The only thing that changed after all that was in device manager under usb serial bus controllers there is an "unknown device". I ran the pc doctor and the report had "removed device: usb mass storage" (this was prior to unknown device showing up".

You never made the recovery discs or youdon't want to use them?

There are two 'other devices' for which no drivers are installed. One I'm pretty certain is the gameport on my audigy 2 zs platinum pro [location = pci bus 2], which isn't supported in vista. the other one is a mystery [location = 'on Msoft ACPI-Compliant System].

I don't care about the gameport but i'd like to get to the bottom of the second device. The thing is the only thing that makes any sense to me in properties/details is in 'siblings' - it looks exactly like the description in the same properties/details for my cpu [athlon 64 x2 6000+] for which there are already 2 instances in 'processors'.

""ACPI\AuthenticAMD_-_AMD64_Family_15_model_67\_0""

etc..

Could this unknown device have something to do with the cpu and might the fact it's unknown be affecting the computer performance?

I can give further info if required. I've no idea what might be needed!

TIA

Question is, how is that supported in Win 10?
If for example Dell only supports this to Win 8, you could try the appropriate Win 8 driver.

Another approach that I have only used 'in extremis' is to use, say, Drivermax (free for 2 drivers a day). This solved a missing driver problem on an HP laptop for me.

I recently decided to to a clean install of Windows 7 7127 RC x64. I have been running Windows 7 x86 because even though I have x64 processors, my laptop came with Vista Ultimate x86 installed on it.

After reading about the differences between x86 and x64 systems and the fact that I have 4GB of memory that only came up as 3GB under x86 I thought I would experiment with Windows 7 x64.

My only problem so far is one unknown device under device manger. I originally had three unknown devices but the first two were based on my Nforce PCI system devices which I finally found here:

nforce Vista driver in Others drivers - Windows Vista Downloads

These are the drivers that worked for my AMD based Nforce system :

Nforce Vista drivers downloads - NVIDIA nForce Driver 15.23 WHQL for WinVista64 Vista driver download - Windows Vista Downloads

After installing the drivers I still have that one unknown device listed. I tried to run DriverMax but it only supports Vista x86 not x64. I also tried PC Wizard and a program called "Unknown Devices" that just tells me I have one unknown device...No Duh!!

I tried to identify the device by PCI vendor ID but it doesn't show one. Since the laptop came with everything pre-installed I have no idea what it can be.

These are the only things I can find to identify it.

I have a portable hard drive that i attach to my computer via USB.
It has worked fine so far but now when i plug it in the only response i get a message saying "USB device not recognized, one of the devices attached to this computer has malfunctioned....." and under Device Manager in Universal Serial Bus Controller Ican see not 1 but 2 Unknown Devices.

If I uninstall them both, unplug the hard drive from the usb port and do a Scan For Hardware Changes then I will get the message "Unkown Device. Device Driver Software installed successfully" and one unknown device will reappear in the Universal Serial Bus Controller.
Now I wonder: what device is that?? Clicking on properties doesn't really help

Plugging in the usb hard drive will bring again the error message "USB device not recognized....." then "Unknown device. Device driver software installed successfully" and the unknown devices number in Device manager back to 2.

The usb hard drive works fine on other computers so that is not the problem

Don't know if I have been very clear in describing the problem but any help would be appreciated.

Answer:Unknown Device In Device Manager

In the future, if you encounter devices in Device Manager with the "Unknown" label on 'em, here's how to track down info that could lead to identifying it. First, open Device Manager, then bring up the Properties for the device in question, then the Details tab. What you're looking for will be on the Device Instance ID entry, looks like this:

What you're looking for is the 4 digit VENdor ID code and the 4 digit DEVice ID code, which for the device in that picture is:

10EC for the Vendor ID code and 8136 for the Device ID code (VEN_10EC and DEV_8136 can be seen plainly in that device identifier string). Take the 4 digit codes and go to:

www.pcidatabase.com

and put 'em in (both at the same time) and then hit Enter or click Search (I find that putting the values into box search boxes and pressing Enter gets a two-field search instead of single-field by clicking one or the other).

That will get you at least on the road to identifying the hardware, but if you're lucky it'll ID the specific device in the search results. Always nice to have this method of tracking down those pesky Unknown device drivers...

Brand-new HP laptop, Windows 10. Under "Other devices" is an entry for "Unknown device" whichshowed up in the last day or two.

After an initial fleetingerror message that was onscreen for only half a second, thedrive worked fine. I didn't try to write to it, but it read with noproblem in File Explorer. I dismounted it before removing it. Device Manager says "Location: PCI bus 0, device 26, function 0".and "Physical Device Object Name: NTPNP_PCI0005". The firsthit on Google for the latter implies that is the Ethernet controller,but none of the other hits say "Ethernet", so I don't really have anyidea what this thing is.

I have recently bought a reconditioned Fujitsu Lifebook S6120.

I have successfully installed all the drivers from Fujitsu's web site. But there is still one "unknown device" - USB BT. Since the machine has an original Bluetooth sticker and the software does not see bluetooth, I suspect this may stand for USB Bluetooth.

The device has the ID

Does anybody know what this means?
Are any drivers available for this device?
