Anybody?!?!?!



Hello peoples,

I have posted this before and unfortunately I still have this problem.
During the boot sequence, when it probes for the USB devices, it causes
a kernel panic (page fault) if there is either (or both) a USB mouse
and/or keyboard attached.

If I remove the mouse and keyboard and let it boot up, then connect
them, they work just fine.

Any ideas?

Thanks
Michael Mercer
