On NetBSD it will recognize the mouse on boot (it lights up). When you
unplug/replug it, this will typicall be noticed on next mouse move (and it
will light up again). You can even plug in a different mouse, and the kernel
will switch to another protocol. X ususaly does not notice anything of this.
Which is especially usefull if you use multiple mice (think a laptop with
touchpad + external mouse). The same is true (but much simpler technically)
for USB mice.
