This one is interesting.
I have two USB keyboard/mouse combination devices here:
- An IBM (0x04b3) IBM Standard USB Keyboard (0x3001).
Mouse has 2 buttons + Z-dir.
- And a Belkin wireless which shows up as something generic
(vendor 0x05fe device 0x1010). Mouse has 5 buttons + Z-dir.
The IBM setup works fine. No troubles in console or X, both kbd and
mouse work as expected.
The Belkin setup works OK initially. But as soon as I move the mouse,
all keyboard and mouse input is locked up. The system is not frozen -
if I reboot, run top and repeat, it continues to run and shows
nothing ominous. The result is the same in console or X.
Since the IBM works, I guess something about the Belkin is tickling a
fairly specific problem somewhere. A ktrace of moused shows:

You can see I waited about 20 seconds before rebooting. Lots of
mouse-wiggling and key-bashing in that time to no avail.
Any ideas where to look next? I'm building a kernel now with debugging
and USB debugging turned on.
