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 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 ddb..... Simple sequence of steps to reproduce problem: ctrl-alt-esc on the USB keyboard db> c Regards, Navdeep
