There is a working usb keyboard driver in the kdb prototype.  I am not
certain about the degree to which the driver is robust or not.  I had
added a uhci implementation to the kdb prototype because I had a uhci
keyboard which didn't work at all.  The kdb usb code is quite complex
and not necessarily the long term approach to the problem.  That means
that if you have a uchi, ehci or ohci port on your board and typical usb
keyboard it has at least the possibility of working.

All these sorts of issues require a good deal of testing and review, 
right now it is at the stage where somethings work, and having other
people contribute to the project would be highly desired.
