NAME
sane-find-scanner - find SCSI and USB scanners and their
device files
SYNOPSIS
sane-find-scanner [-h|-?] [-v] [devname]
DESCRIPTION
sane-find-scanner is a command-line tool to find SCSI and
some USB scanners and determine their Unix device files.
It's part of the sane-backends package. It checks the
default generic SCSI devices, e.g. /dev/sg? for Linux and
the their USB pendants (e.g. /dev/usb/scanner0). Also
/dev/scanner and /dev/usb/scanner are checked. The test is
done by sending a SCSI inquiry command and looking for a
device type of "scanner" or "processor" (some old HP scan�
ners seem to send "processor"). So sane-find-scanner will
find any SCSI scanner even if it isn't supported by any
SANE backend. For USB devices, the corresponding files are
opened and the vendor and device ids are determined if the
operating system supports this feature. Currently USB
scanners are only found if they are supported by the Linux
scanner module or the FreeBSD uscanner driver. sane-find-
scanner won't find parallel port scanners, or scanners
connected to proprietary ports.
OPTIONS
-h, -? Prints a short usage message.
-v Verbose output. Show every device name and the
test result.
devname Test device file "devname". No other devices are
checked if devname is given.
EXAMPLE
sane-find-scanner -v
Check all SCSI and USB devices for available scanners and
print a line for every device file.
sane-find-scanner /dev/scanner
Look for a scanner (only) at /dev/scanner and print the
result.

BUGS
No support for parallel port scanners yet. USB support
should be extended to other platforms and scanners. Detec�
tion of USB vendor/device ids should be extended, if pos�
sible.
