(same for keyboard) We don't need to specify this I believe. Dynamic allocation would do fine I think, especially if you only do a hand-off. But a much better solution would be to create a mouse bus attaching to the root bus, and connect all the mice to that one. Unit numbers will be increasing, so we will only need one major number for that one, one naming scheme, like mouse[0-9]+, in /dev. Sysmouse could integrate with that as well. Dynamic attachment and detachment is straightforward or automatic, implemented in the mouse bus.
