Hello and welcome to the forumCould you expand the Propriete list and show Hardware ID values?It'd be more informative if you'll show this unknown device in the devices tree:choose "Devices by connection" in the Device Manager' View menu, expand the tree and find out this unknown device. What are its parent devices?BTW, is win7 installed from official ms image or it's a custom package? Did you install drivers using Lenovo ThinkVantage System Update application? Is an Intel Chipset Driver installed?

I have Windows 7 Ultimate. Since very recently an unknown device keeps popping up in the device manager every time I start Win. It's reported location is within the front USB root hub but I haven't changed there anything lately. The device status reports "Windows has stopped this device because it has reported problems (Code 43)". I can uninstall/disable it but it will get picked up again the next time I reboot.

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 solved this issue (see my other post) with the help of Lenovo support techs by rolling back the HD Audio Driver in Device Manager.  Changed it from the Lenovo-supplied Conexant HD Audio driver to the generic Microsoft HD Audio driver.  CPU usage is now running at <1% for the "Windows Audio Device Graph Isolation" process in Task Manager, whereas prior to rolling back the Conexant driver CPU usage was a constant 15% to 30%, and it occasionally spiked at much higher levels (on two occasions in excess of 90% CPU usage for the 'WADGI' process).  Everything's been fine since the rollback, but I am wondering if anyone else has experienced this with their 2017 X1 Carbon?  I don't think it's a sound card (hardware) issue because CPU usage is normal when using the Microsoft driver and there is nothing wrong with the audio output or mic input.  I'm thinking it has to be poorly written s/w code for the Conexant driver, but would like to hear any other views on the subject, especially if you've had a similar experience.  When I was experiencing higher CPU usage with the Conexant audio driver it also caused the fan to kick in a lot more often, of course, particularly when other processes were in play, but now the machine is very nearly always fan silent, with only occasional, momentary spikes of fan use, which is normal.

If you go to the unknown device and right click>details>hardware ID's (see pic). Copy the hardware ID and google them. that will tell you who makes the device. You can then go to the mfr website and get the driver.

Hi everyone,
So first I'll give you basic information about my computer and then I will tell you the rest. First my computer when bought came pre installed with Windows 7. As soon as Windows 8 came out I upgraded to Windows 8. My system is BIOS not UEFI. I have about 3gb ram and 500gb hdd drive 2.20 ghz processor. Windows 8 runs really smoothly. So recently 2-3 days ago I decided to dual boot Ubuntu with Windows 8. Before when I had Windows 7 I dual booted it with Windows 8. So now I thought about dual booting with Ubuntu 12.04 LTS. The Installation process was fine until I take out the installation usb with Ubuntu and whenever I try to restart it the PC would hang on the oem screen for a while which is ridiculously long. Then when I would boot into Windows 8 and sign in I would get a notification message saying the last storage device you plugged in isn't found. I went to the device manager in Windows and it would say an unknown device has been found and even if I tried to Uninstall it would come back again. I tried searching for updates but nothing came up. I googled it and got no results. If you guys can get me the problem solved it would be great. What annoys me the most is the PC hanging on the oem screen. Right now I fresh installed Windows 8 so it's the only OS running at the moment. But I want Ubuntu 12.04 LTS because of git, ssh and all the server side stuff. I have also posted the error screenshot for more info.

Thanks,

Gurinder Hans

Greetings SummaSTJO,
Thanks for your question.
There's a Smart Connect driver listed under Windows 8.1 on our page. We sometimes recommend you simply try the previous OS version driver and see if it works for you. If the installer doesn't work the raw files are included in the package in case you want to manually install it through device manager.
Deployment of the driver is beyond my scope and you likely know more about that than me.
Here's the 8.1 driver: www.dell.com/.../DriversDetails

After almost 2 years of near flawless performance, my aging computer is giving me some trouble. Orginally a Windows 98 IBM Aptiva 600mhz PII, 64 meg, 20 gig; I have added another 128 meg, an 80 gig WD as slave with only my massive music collection and upgraded to Win 2K (that's when it became near flawless, before that it was a P.O.S.)

Here's the problem, somewhat randomly, my computer just locks up. Control+Alt+Delete does nothing and the mouse pointer is stuck. The only way to recover is to turn it off manually on the tower.

Usually when this occurs, there is some kind of distortion in the display. Sometimes, somewhere between 2/3 and 3/4 of my screen will turn a solid color, usually green, sometimes I can still use my mouse and run programs when this happens, but again the only way to get things back to normal is to restart. Sometimes when it completely locks up, some of the screen looks like it has shifted to one side, with some distortion in the colors.

I went to PC Pitstop and their test showed that I have a disabled device, the device was labeled as "error code 28". My device manager shows no problems. When I went to MS.com, I found that the 28 code refers to a driver issue, but I have no idea what driver is giving me problems. I don't know if this is related, but who knows?

Anyway, thanks for taking the time to read my lengthy post and I would appreciate any responses.

Thanks,
KC

I've been working on a friends Dell Inspiron mini 1011. Initially She could not get onto he wireless network.
She had someone else get rid of malware on it. I'm not sure what they did, but there were three devices in
Device Manager- including the wireless card- that were not installed.
One device was marked unknown and is the only one I cannot figure out after looking through Dell's
driver page using servicetag. The device Instance ID is ACPI\CPL0002\2&DABA3FF&0. Looking at its
properties, I see it has a status code 1. Microsoft says "This is very common with universal serial bus (USB) and Institute of Electrical and Electronics Engineering (IEEE) 1394 composite devices...." The System Information tool > components > Problem Devices shows nothing.
Google revealed it is most commonly fixed by installing smart battery or battery meter software. No luck with that. It MAY be bluetooth- BT is enabled in BIOS. WIDCOMM software does not detect a BT device.

Except that all was installed.I was looking for solution here, tried to install Energy management and other exe files linked in replies but also it didn't help... Can someone help me with finding correct driver for this device for Windows 7 x64?

Note: Device manager lists appropriate bluetooth antennae.  Some items are still showing up ok, but many (some new, some previously paired) are listed as unknown now, so they are useless to me until this is resolved.  This is a fairly new Flex5 (bought at Microcenter about a month ago).I ran the Lenovo "Vantage" program to get the latest bluetooth drivers on board.Tried uninstalling BT driver and running manual install of intel and Qualcomm drivers.  Windows10 is not seeing the Intel ones, I think as when I try to change the driver to the intel ones I only see the the QualcommAtheros and the generic bluetooth drivers available.  I ran that installation a number of times, but havn't been able to try the Intel drivers yet.  I'm not sure if they will fix the problem, but would like to try them, unless someone here can point me at something else that may be the cause.  Thanks for any info!

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

A: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.

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.
 

A: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.

I have a unknown device in device manager. When I plug in my power cord to charge i get a black screen as soon as i unplug the windows screen comes back. Not sure if these are related or not.

A: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.

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

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

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.

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
