Try doing that with /dev/ums0 after killing moused. I would imagine it
would do the same. I installed PC-BSD on the same box and tried several
USB mice. Still no worky. I think I have some kind of bug either in
the mother board, or in FreeBSD, because I had tried installing WinXP
over it and the USB mouse worked. Really weird. I think I will
probably have to use a PS/2 mouse on this box.
