I just got my B&W G3 400/ 128M ram/ 4G hdd (I know, crappy specs, whatcha gonna do? ) up and running with a third party (don't reamember the brand) DVD burner in it so that I could install OS 10.2.4 from DVD. The installation goes fine, I just start ist up, run Disk Tools to wipe my whole drive and install. Simple. Or is it? Every single time I boot the computer up after installing OS X, no matter what mouse I use, the mouse isn't detected. It doesn't detect clicks, it doesn't detect movement, nothing. I know the mouse SHOULD work, because it worked just fine when i was installing OS X, but now i'm not getting anything (my keyboard still works, too) any ideas?
