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.
