[sane-devel] Umax Astra 1200S freezing up

I have two SCSI cards in my computer. An ISA Buslogic BT-545C card and a 
PCI Adaptec 2940 card. I attach my slow devices to the Buslogic card: 
Zip drive, 1X SCSI cdrom, and the UMAX scanner. To my Adaptec I attach 
my fast devices: disk drive and Yamaha CDRW drive.

I don't recommend the Buslogic card since as best as I can determine it 
is not being maintained in the 2.4 kernel. The driver has problems and I 
am not aware of a fix. I use it but have to use 10 bit mode always and 
set "option scsi-maxqueue 1" in the umax.conf file to work around 
problems. It does work fine with these settings.

When I attach the UMAX scanner to my Adaptec card my CDRW burner will 
have random bit errors when it tries to burn a CDR. But, with the UMAX 
on the Adaptec card it works fine. But on both cards I do have to 
disable SCSI bus resets in the SCSI bios in order for it to work.

There are probably many other better options for scanners. What I like 
about the 1200S is that they are pretty cheap on EBAY if I ever need a 
replacement part.
