NAME
     sane-find-scanner  -  find  SCSI  and USB scanners and their
     device files

SYNOPSIS
     sane-find-scanner [-h|-?]  [-v] [-q] [-p] [-f] [-F filename]
     [devname]


DESCRIPTION
     sane-find-scanner  is  a  command-line tool to find SCSI and
     USB scanners and determine their Unix device files. Its pri-
     mary  aim  is  to make sure that scanners can be detected by
     SANE backends.

     For SCSI scanners, it checks the default generic SCSI device
     files  (e.g.,  /dev/sg0) and /dev/scanner.  The test is done
     by sending a SCSI inquiry command and looking for  a  device
     type  of "scanner" or "processor" (some old HP scanners seem
     to send "processor"). So  sane-find-scanner  will  find  any
     SCSI scanner connected to those default device files even if
     it isn't supported by any SANE backend.

     For USB scanners, first the USB kernel scanner device  files
     (e.g.   /dev/usb/scanner0),  /dev/usb/scanner, and /dev/usb-
     scanner) are tested. The files are opened and the vendor and
     device  ids are determined, if the operating system supports
     this feature. Currently USB scanners are only found this way
     if  they  are  supported  by the Linux scanner module or the
     FreeBSD or OpenBSD uscanner driver. After that  test,  sane-
     find-scanner  tries to scan for USB devices found by the USB
     library libusb (if available). There is no special USB class
     for scanners, so the heuristics used to distinguish scanners
     from other USB devices is  not  perfect.   sane-find-scanner
     also  tries  to  find  out  the type of USB chip used in the
     scanner. If detected, it will be printed  after  the  vendor
     and product ids.  sane-find-scanner will even find USB scan-
     ners, that are not supported by any SANE backend.

     sane-find-scanner won't find most parallel port scanners, or
     scanners  connected to proprietary ports. Some parallel port
     scanners may be detected by sane-find-scanner  -p.   At  the
     time  of  writing this will only detect Mustek parallel port
     scanners.


OPTIONS

             used twice, SCSI inquiry  information  and  the  USB

             device descriptors are also printed.

     -q      Be quiet. Print only the devices, no comments.

     -p      Probe parallel port scanners.

     -f      Force  opening  all explicitly given devices as SCSI
             and USB devices. That's useful if  sane-find-scanner
             is wrong in determining the device type.

     -F filename
             filename  is a file that contains USB descriptors in
             the  format  of  /proc/bus/usb/devices  as  used  by
             Linux.   sane-find-scanner  tries  to  identify  the
             chipset(s) of all USB scanners found in such a file.
             This option is useful for developers when the output
             of "cat /proc/bus/usb/devices" is available but  the
             scanner itself isn't.

     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 (SCSI) scanner only at /dev/scanner and print the
     result.

     sane-find-scanner -p
     Probe for parallel port scanners.

SUPPORTED PLATFORMS
     USB  support  is  limited to Linux (kernel, libusb), FreeBSD
     (kernel, libusb), NetBSD (libusb), OpenBSD (kernel, libusb).
     Detecting the vendor and device ids only works with Linux or
     libusb.

     SCSI support is available on Irix, EMX,  Linux,  Next,  AIX,
     Solaris, FreeBSD, NetBSD, OpenBSD, and HP-UX.


BUGS
     No support for most parallel port scanners yet.
     Detection of USB chipsets is limited to a few chipsets.
