I have problems with USB on a VIA based MB... but only when running a MP
NetBSD and Linux kernels.  The USB works fine with an SP kernel, works
fine with Win2k (dual-proc) and fine with a Linux SP.  Haven't tried
FreeBSD MP.

Near as I can figure, the device is generating an interrupt which isn't
being properly routed.  The USB is the only device interrupting on INTD
(the below dmesg may or may not be verbose enough to show).

ISTR someone was looking to redo much of the interrupt routing code, so
I've mentioned this before, but haven't made a big fuss about it.  I
would love to be able to use USB on this machine.
