You need "configured mouse" to deal with external mice that you may plug 
in to a USB port.

As for the event2/event3 thing, it may be that you have an external 
mouse plugged in that's getting event2 sometimes. There may be other 
factors. You can always write udev rules to symlink the built-in 
devices to fixed names.
