USB mouse "hang" with 2.5.75

[crozierm@consumption.net]

Hello,

I'm experiencing odd USB mouse behaviour with 2.5.75 & 2.6.0-test1.  Those
are the only 2.5.x flavors I've used on this particular computer, so I
don't know if this is something new.

While using the mouse normally, it will suddenly stop responding.  If I
cat /dev/input/mice and wiggle the mouse, nothing is returned.  No extra debug messages appear in the
syslog until I unplug the mouse and plug it back it, at which point
everything works normally.  I can't find specific steps to reproduce it,
but with persistent use I can usually get it to hang up within a minute or
two.

Also, if I leave XFree86 and go to the console, then switch back to
XFree86, the mouse is restored.  Because of this I thought it must be X,
but this has never happened with 2.4.x.

Below is usb debug logging and system info.  If I can provide any other
information, please respond to me directly, as I'm not on the list.

The mouse is a logitech optical usb mouse.  More info below in the usb
logging.
