Hmmh, what version of FreeBSD and what SCSI controller are you using?
I find it strange that a user-level SCSI program would hang the entire
system. I suppose it might be possible for the scanner to block the
SCSI bus if something bad happens, but it should not lock up the
entire system. Hence I wonder whether the problem might be with the
generic SCSI driver, rather than the UMAX backend.
