This is sane-find-scanner from sane-backends 1.0.25git # sane-find-scanner will now attempt to detect your scanner.

Usage: sane-find-scanner [-hvqf] [devname ...] -h: print this help message -v: be more verbose (can be used multiple times) -q: be quiet (print only devices, no comments) -f: force opening devname as SCSI even if it looks like USB -p: enable scanning for parallel port devices
