Ok guys, I think I found the problem. I did a little more searching, and apparently the mouse
has to be USB to work. Oh well.
But it seems strange; it said it had "USB mouse
and keyboard support", so why doesn't it have issues with my keyboard, too? It's also PS/2.
Well, I have an extra one (just because,
) that
is USB, but it doesn't seem to work at all with the OS.
