[ANNOUNCE] The USB ehci/uhci for KDB

My hack was too lame to post, I thought--I set i=0 before the indirect
call to urb_complete. :)

I didn't sort all the cases out, but on some exits from the loop for i
to KDB_USB_NUM_KEYBOARDS, i has a value corresponding to a non-present
keyboard--so the attempt to get a urb_complete function pointer (last
statement in get_usb_char) from that element in the keyboard array is
illegal.
