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. :-) > I have several questions that I would very much appereciate an answer to: > > Is it normal for sane-find-scanner to find my scanner "twice" (see below) ? 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. > Once sane freezes, can I reset the SCSI bus without rebooting ? I could not find a way. That only prevents the scanner from being detected again. > What specific options should I try in umax.conf (or is it a SCSI problem > whose solution lies elsewhere) ? 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 one. -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. Hub
