I've been able to reproduce your problem on 3.2R+PAO3, and will
furnish a patch from the BSD-USB mailing list. Also, if you
start having trouble with the USB mouse, try changing the order
of the usb _devices_ in the kernel config file; something
happened recently, I think, to change the probe order relative to
that in LINT, and it causes the mouse to be found on the probe to
ugen0 (but I am not sure of the technical details). You need to
create /dev/{ums0,usb0}, if you have not done so.
Patch relative to /usr/src/sys:
