I an HP Scanjet 4C scanner (SCSI address 1, Termination On) hooked to
the external SCSI port on a Buslogic BT-930 Ultra SCSI Host adapter. It is the
only device connected to this card.
The O.S. is Redhat Linux 5.2 with kernel 2.0.36 (all drivers compiled
in statically, including SCSI generics). The card is the 2nd SCSI host. The
system drives are connected to a BusLogic BT-950 PCI Ultra Wide card. The 930
recognizes the scanner at bootup as does the kernel, and lists it in
/proc/scsi/scsi with the correct vendor name, model, and SCSI address.
I have the sane-1.00-1 RPM installed, and when I try scanimage -d
hp:/dev/sgb or scanimage -d hp:/dev/scanner (a sym-link to /dev/sgb) the system
freezes and I have to COLD boot in order to get it back. I have tried settign
the Debug levels to 128 and scanimage -d hp:/dev/scanner -h and a bunch of
cryptic stuff spits up on the screen but I can't capture the output as the
system freezes before any of it gets written to the disk.
