I tried using the updated file, but the problem stubbonly persists.

Here is the log of events. Again, it is in 3 sections: with mouse and
keyboard plugged in, with mouse and keboard plugged in but with switchbox
switched to another port, and without keyboard plugged in.

1. Mouse and Keyboard Plugged In
========================
This is the working, standard case.

pckbc_send_devcmd: 0


2. Mouse And Keyboard Plugged in, Switchbox to another Port
===========================================
This is the case where things fail. The machine is booted up in this state,
and then the switchbox is switched to the booted machine. The keyboard does
not work.

3. No Keyboard Plugged In
===================
This is the case where the keyboard is plugged in after boot-up, and works.
It essentially removes the switchbox from the equation.

In both case 2 and case 3, the keyboard is correctly assumed to not be
plugged in. The difference seems to be in the probing of the mouse. Now this
seems particularly strange, as the switchbox is just a keyboard/monitor
switch. The mouse is constantly plugged in.

Thank you to anyone who has looked at this. If there are any suggestions for
where to probe further, they would be appreciated.

Thank you.
