No, but the next very obvious questions are:
- does the keyboard work with another computer? (so we know if the 
keyboard is not broken)
- does the another USB keyboard work? (so we know if it is a specific 
problem with your keyboard)
- does changing the USB port do something?
- do Xorg logs say anything?
