    USB Keyboard stopped working, but only in Windows - drivers?


    When I plug in my USB Keyboard (Microsoft Comfort Curve 2000), an "Unknown device" shows up in Device Manager:



    Occassionaly the keyboard is showed correctly as "Comfort Curve 2000" but still with this yellow triangle. When I uninstall "unknown device" and plug in keyboard, this shows up:



    The keyboard was working perfectly before 15 February. During 15-24 February period I didn't use it at all, and today (25 February) it doesn't work. During this time I installed drivers to pciexpress usb 3.0 and a couple of windows updates. I uninstalled them both, but still no luck.

    The keyboard works both in BIOS and other computers, so both USB port and the keyboard are fine. I once managed to use it in Windows after restart (not sure how) but it stopped working after a couple of minutes (perhaps it tried to find "better" drivers?).

    I don't care if it'll be recognized as Microsoft Keyboard, generic USB keyboard driver would be just fine, but choosing it from drivers list doesn't help.

    I tried to remove all keyboard-related devices from Device manager and rebooting.

    How would you go about it? Note: I don't have any restore points.

    Yes. And this is what happens:



    I just want it to work as generic usb keyboard at least, I don't care much about special function keys...

    Is there any Error code .. I take it you have tried it in different USB Ports .. What about other Devices do they work on all USB Ports ..

    No error code unfortunately (or am I missing it?). I've tried different devices in this port and also keyboard in other ports. The ports are fine.

    The drivers for this device are not installed. (Code 28)

    There is no driver selected for the device information set or element.

    I know you have stated the Keyboard works on other Computers .. But i think the problem is more than likely a faulty Keyboard will work some times only .. It would be a good idea to get another Keyboard and try it .. That should determine what the problem is ..

    @Layback:

    me too :)

    When I manually pick "USB...Comfort Curve" from a drivers list, the device status changes to:
    This device cannot start. (Code 10)

    The same with "Standard Microsoft Keyboard".

    @maxie:
    OK, I'll try to find someone with similar Microsoft Keyboard and check if it works. I'd be happy to buy another keyboard but first I need to know this will solve problem.

    If anyone has this exact keyboard, could you send me .inf that you're currently using?

    Let's take a look at what Device Installation is doing (may find a hint in the DevMgr trace log)

    Download/unzip the attachment.

    > Delete C:\WINDOWS\inf\setupapi.dev.log
    > Double click SetupAPI LogLevel Very_Verbose.reg. Allow the registry change to take affect
    > Reboot. Plug in the keyboard. Wait till no driver found error
    > Change extension C:\WINDOWS\inf\setupapi.dev.log to C:\WINDOWS\inf\setupapi.dev.txt

    and attach to next post
