I recall I did have some problems with the keyboard hanging on reboot after
installation of the camera and other devices which took there power from
the keyboard. Perhaps if you sent more details of your computer to the
CU-list we could fathom this problem out. My installation seems to work ok
now. I didn't have any problems with software, instead it was my keyboard.
I think something similar happened when I hooked up an external removeable
drive which also took power from the keyboard. If you have a PS2 mouse
socket you could try that instead. You may need to get a small adapter if
the socket is to large. I would avoid trying to use an adapter to change a
normal serial port to a PS2, many motherboards simply refuse to work with
these adapters.
