sane-hp5400 - SANE backend for Hewlett-Packard 54XX scanners


   The  sane-hp5400  library  implements  a SANE (Scanner Access Now Easy)
   backend that provides  access  to  the  following  Hewlett-Packard  USB
   flatbed scanners:

          ScanJet 5400C
          ScanJet 5470C
          ScanJet 5490C

   More   details   can   be   found   on   the  hp5400  backend  homepage

   This is ALPHA software. Keep your hand at the scanner's plug and unplug
   it,  if  the  head bumps at the end of the scan area. See also the BUGS

   If you own a scanner other than the ones listed above that  works  with
   this  backend,  please  let us know this by sending the scanner's exact
   model  name  and  the  USB   vendor   and   device   ids   (e.g.   from
   /proc/bus/usb/devices,  sane-find-scanner or syslog) to us. Even if the
   scanner's name is only slightly different  from  the  models  mentioned
   above, please let us know.


   The  contents of the hp5400.conf file is a list of usb lines containing
   vendor and product ids that correspond to USB scanners.  The  file  can
   also  contain  the  names of device files that correspond to an HP 54XX
   scanner.  Empty lines and lines starting  with  a  hash  mark  (#)  are
   ignored.   The  scanners  are  autodetected by usb vendor_id product_id
   statements which are already included  into  hp5400.conf.   "vendor_id"
   and  "product_id" are hexadecimal numbers that identify the scanner. If
   autodetection does not work, add the device name of your scanner to the
   configuration file, e.g.  /dev/usb/scanner0.


          The   backend   configuration  file  (see  also  description  of
          SANE_CONFIG_DIR below).

          The static library implementing this backend.

          The shared library implementing this backend (present on systems
          that support dynamic loading).


          This environment variable specifies the list of directories that
          may contain the configuration file.  Under UNIX, the directories
          are  separated  by a colon (`:'), under OS/2, they are separated
          by a semi-colon  (`;').   If  this  variable  is  not  set,  the
          configuration  file  is  searched  in  two  default directories:
          first,  the  current  working  directory  (".")  and   then   in
          /etc/sane.d.  If the value of the environment variable ends with
          the directory separator character, then the default  directories
          are  searched  after  the explicitly specified directories.  For
          example, setting SANE_CONFIG_DIR to "/tmp/config:" would  result
          in   directories  "tmp/config",  ".",  and  "/etc/sane.d"  being
          searched (in this order).

          If the library was compiled with  debug  support  enabled,  this
          environment  variable controls the debug level for this backend.
          Higher debug levels increase the verbosity of the output.

          Example: export SANE_DEBUG_HP5400=4

   Scanning is only tested with Linux/ix86/gcc. Be careful when testing on
   other  operating  systems  and  especially on big-endian platforms. The
   scanner may get wrong data.
