$ pkg_info | grep screen
xscreensaver-5.00   Save your screen while you entertain your cat

The box is a Dell Optiplex GX520, with a Radeon 9200 Pro configured for
dual-head.  I'm using the radeon driver.  Mouse and KB are USB.

Symptoms are that every so often, when returning from the screensaver,
I have no mouse.  This happens about once a day on average, although
I've been able to discern no other pattern or event that triggers it.
Most of the time, when I come back from screensaver, everything is fine.

When the problem occurs I can get mouse function back by waiting until
the screensaver starts again, when I move the mouse or hit a key to
disable the screensaver the second time, all is well.

I've tried unplugging/plugging the USB mouse, but this doesn't help.

Occasionally, I get these messages in /var/log/messages:
Sep 12 08:38:20 vanquish kernel: uhub5: vendor 0x0424 product 0x2504, class 9/0, rev 2.00/0.00, addr 2
Sep 12 08:38:20 vanquish kernel: uhub5: multiple transaction translators
Sep 12 08:38:20 vanquish kernel: uhub5: 4 ports with 4 removable, self powered

... as if the mouse were recently plugged in.  The appearance of these
messages does _not_ coincide with the problem.

Any thoughts on what could be wrong?  I'm not sure whether this is a
problem with xorg or FreeBSD, but I'm suspecting FreeBSD because of the
messages.  Any suggestions on how to debug?
