You have to know that USB controllers can emulate the old 8042 driven keyboards in hardware, but this won't allow using other USB devices at the same time. As long as FreeBSD isn't touching the USB controller the emulation would be kept. You should take a lock into the BIOS setup if you can change USB keyboard legacy support. And you should lock into boot messages if there is a non working USB device found. The USB legacy thing is just an assumption - it could be something completely different as well. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
