Sony VAIO Z600TEK, current just before gcc 3.1.
Having tested the usb subsystem a few weeks ago (it hung during resume), I
decided to try after the latest fixes from Joe. kldload usb; kldload ums
and I plugged my optical mouse (see below the messages).
Then I suspend/resume the machine. This time it didn't hung (thanks Joe!)
but the mouse wasn't functionning. Killing and restarting usbd gave
nothing. I then decided to kill moused: instant panic...
Joe, any idea?
