I have tested this with it plugged in during boot-up and running
kudzu, and while attaching it to a running system.  For clarification
I will describe attaching it to a running system.

I have a 4 port usb hub that has a keyboard + mouse attached.  I plug
the hub into my 1 usb port and I observ the following from
/var/log/messages:

/proc/bus/usb/devices does not show the attached mouse:

The same result occurs if I unplug and re-plug the hub.  The only time
I can get it to recognize the usb mouse that is plugged into the hub
is if I remove the mouse and plug it back into the hub.  I then observ
the following changes in /var/log/messages:

and now /proc/usb/bus/devices reports the mouse correctly:

I have tried different ports on the hub, I've tried booting with the
hub installed.  All of these do not get the mouse recognized.  Only
unplugging and re-insterting the USB mouse seem to work.  I would
blame faulty hardware if it weren't for the /var/log/messages seeing
the mouse input device (just not activating it).

Thoughts, suggestions?
