So there is a chance I'll get this to work some day :)

I use the patch from Kurt Garloff, version 1.41 with old error
handling, built as a module for a vanilla 2.4.20.
Although this time I didn't get any oopses or panic(), I still get
error messages about SRB abort. With previous versions of SANE I used
to get this message at the second scan, then scanimage got stuck and I
could just reboot the machine. (see below)
Now I can perform several scans in a row without problems, however
after a few minutes of inactivity, the same problem occurs.
It seems to be the scanner that goes to sleep or something like
this. Firmware is version 3.11 on the scanner, I could update it
provided there is a windows NT 4 driver, because that's the only
windows box I can get to... But the latest driver version for this
scanner is ScanWizard 2.54 and I remember I installed this version
Error messages :
DC395x: Target 06: No sync transfers
Seems like the driver cannot achieve a bus reset, but I'm absolutely
no SCSI expert :/ The scanner is id 6 on the bus, and is the only
device attached to the adapter.
