Check in Device Manager to make sure your USB ports are listed properly.

You can also try to reset the BIOS (if desktop, unplug from power, remove the CMOS battery for 15 seconds, replace, reboot. If laptop, need to check in the manual).

When did this start? Anything get installed, uninstalled, error messages, etc.. before this started?
