Amen. I have an Astra 1220S, a PowerCenter Pro 240 (basically a 7300
with a bumped up CPU and a real video card) and it fails miserably
aswell when the scanner is plugged on the internal SCSI controller
(the NCR one).
So I'm not alone. :-)

Sort of. You have 2 /dev/sg device that points to the same real SCSI
device. It does it for me because /dev/scanner is a link to the sg
device it is on.

I could not find a way. That only prevents the scanner from being

If there is a solution, I'd like to know.
Think I haven't tried:
-moving to 2.4 kernel (still use a 2.2.20), but apparently you have
-using the AHA 2930B card for the UMAX. Last time I tried, I could no
longer boot (my boot disk is on this controller).
Side note: my CoolScanIII LS30 works like a charm in this AHA 2930B. I
haven't tried on the other controller due to lack of proper SCSI cable.
