This backend is based upon the Tamarack backend and adapted to the Avision
|
|
scanners by René Rebe and Meino Cramer.
|
|
|
|
This file implements a SANE backend for the Avision SCSI Scanners (like the
|
|
AV 630 / 620 (CS) ...) and some Avision (OEM) USB scanners (like the HP 53xx,
|
|
74xx, Minolta FS-V1 ...) or Fujitsu ScanPartner with the AVISION SCSI-2/3
|
|
or USB command set.
