I finally got a chance to try a USB keyboard with ddb, and things did
not go too well overall.  While inside ddb, keystrokes were recognized
properly and repetition worked too.  But after exiting ddb, the
keyboard wouldn't work - there wasn't any visible response to
keystrokes.  Also, I kept seeing the login prompt continually scroll
up, as if someone was pressing <return> repeatedly.  It certainly
wasn't me :-)

Are you assuming that a user will not resume normal operation after
entering the debugger?  A panic/reboot isn't the only exit route from

Simple sequence of steps to reproduce problem:
ctrl-alt-esc on the USB keyboard
db> c<return>
