I would of thought that myself buti have now had a chance to really look at
the problem and puzzling to say the least is how best you could describe it.
Using standard ps/2 mouse the machine boots fine and does not seem to hassle
at all. I found that the pc would take excessive time between the text boot
of windows xp and the gui during the inialization of the usb devices only
when the USB mouse was connected. Then when in windows the mouse wouldnt
work and you had to unplug it and then reconnect it and it would work. I
grabbed a new mouse of different model and booted up and went quickly, only
because it hadnt been added to the device list yet. On reboot the same thing
happend again, as well as not being usable unless unplugged and replugged
back in. I would watch the optical sensor on the mouse switch on and off
multiple times during this wait period. as for drivers ... the running off
the standard hid compliant drivers. Strange huh?
