This is due to the Mustek scanner being unfriendly on the SCSI bus.

It will not disconnect, though it stays on the bus for _very_ long times,
as it scanning speed is rather slow.

This means that you should most probably get another SCSI-card (a very cheap
one will do) for the scanner, as it blocks the bus while scanning which
is not good, if you need access to the scsi-bus in the meantime.

Anyway timeouts need to be raised for other drivers, too.

Don't know for the Buslogic card. Grep for "timeout". But I assume the
problem might persist, due to the unfriendly behaviour of the scanner.

Don't know yet. Could be CZ, could be SP ... Mustek seems to be continously
giving new names to their products.
We will find this out, when we see the images ;-)
