I recently moved my computer and when I reattached all my usb devices some were working as before and windows tried to install drivers for others. The once it attempted to install drivers for were working at login (like my usb keyboard) but failed as windows could not find a suitable driver for them. It seems to be the case that devices connected to the same usb port before the move still works while those devices that have changed ports do not.
In device manager the devices are listed by name (logitech illuminated keyboard, etc.) but without a functioning driver. I have tried to remove and reinstall and redownload the official logitech drivers. No luck.
This is definitely a windows issue. The keyboard works both in the BIOS menu and in Ubuntu (run from a live cd).
