I hope this helps:

Test box: FreeBSD 8.0-RC1 amd64 r197323M on Asus M2A-VM (SB600)

Without your patch, if mouse is plugged into one of the back USB ports and
umass device is present on any USB port, mouse won't work. It has to be
connected to front USB port to be friendly with other devices.

With your patch, mouse can be plugged anywhere, it won't complain about
umass devices connected to front USB port, but it still doesn't play nice
with devices on back ports during boot. If I connect storage device after
boot, both mouse and storage devices work fine.


Parts of dmesg with mouse connected to back and storage to front USB ports.
Everything works.
