Generic SCSI scanner driver

Is there such a thing as a generic SCSI scanner driver ? Or is there a standard set of SCSI commands for scanners ? I have that old Relisys VM 3530 (Relisys is just a reseller, I don't know about the real manufacturer) which is like new and used to work beautifully with my Amigas. I wish I could use it with sane/xsane. Is it worth a try ? Which driver/settings should I try ? Of course I have a Tekram DC-390 controler to plug it in. Any similar experience ? Thanks for the help. -- ~adj~ Ces mystères nous dépassent Feignons d'en être l'organisateur...
