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

SYNOPSIS    [Toc]    [Back]

       sane-find-scanner [-h|-?]  [-v] [devname]

DESCRIPTION    [Toc]    [Back]

       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  sanebackends
  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 scanners 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    [Toc]    [Back]

       -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    [Toc]    [Back]

       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    [Toc]    [Back]

       No support for parallel	port  scanners	yet.  USB  support  should  be
       extended  to  other  platforms  and  scanners.  Detection  of  USB vendor/device
 ids should be extended, if possible.
