Can you generate and send a log with debug level set to 8 and the dprintf in usb-hid.c:handle_key() changed to 8? Getting timestamps on the log (as with tools/readserial.py) would also help. > With this change, I am able to type well enough to get windbg started, > which is all I needed at the time.

Yeah - since the loop was disabled there's no longer a queue on USB key events. This means any keys pressed faster than 55ms are dropped. -Kevin _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
