Windows 7: Unknown Device

Microsoft Windows 7 Ultimate 64-bit 7601 Multiprocessor Free Service Pack 1
 
 
Unknown Device

Hi all. Since installing Windows7 64bit, I have an 'unknown device' (see pic). I've not installed any new hardware except 4GB RAM but that's been recognised by Windows already. Any way I can find out about this device so's to get rid of the warning triangle?

Many thanks.

USB driver

Maybe win 7 doesnt have a driver for whatever that is. You could try unplugging usb devices (safely) and checking to see if that usb port is referenced to a specific piece of hardware. I had an external usb HD that was no problem in vista but there wasnt a driver for it in win 7 beta. After driver install no problem. Just guessing though

Good Luck

Thanks for that. However, my PC is very basic - no USB devices bar modem and that works fine...

By going to the Details tab and using the drop-down list, you will get the ID codes of the offending device. You may get lucky with a Google or Bing search of those codes to someone else who figured it out.

Bye.

You could try uninstalling the device in device manager then Windows will attempt to connect to Windows Update to find drivers. Since it acts as a newly installed device Windows will do a more thorough search for drivers.

Hope this helps

may be just dust or dirt in your port, try a can of compressed air and clean out ports and then reboot, good luck to you

I really am grateful to you all for the suggestions. But guess what? It's gone. I've just been using a memory stick with my bank passwords etc on it so maybe that had something to do with 'clearing' the system. Anyways, thanks again. Darn good forum this...

Glad it's sorted mate

What is the exact device? Some other people may benefit from information in this thread if they have the same hardware.

Ah, that's the point - there was no device. The yellow warning triangle just appeared out of nowhere, either when I switched to x64 or soon thereafter. Musta been a blip of some kind.
