If you have plugged/unplugged any of the ADB devices while the machine is
on, you may have blown a fuse on the motherboard.  To my knowledge, it is
soldered on the motherboard, so it requires a board swap.  You could try
attaching the keyboard and/or mouse to another system for verification, or
try attaching a different keyboard using a different cable...
