        sane-hp_rts88xx  -  SANE  backend  for  scanners  based  on the RTS8891


        The sane-hp_rts88xx implements a SANE (Scanner Access Now Easy) backend
        that  provides  access  to RTS8891 chipset based scanners. This backend
        will try to support the following models:
        MANUFACTURER:    MODEL:         USB ID:
        ---------------  --------------  ---------
        Hewlett-Packard  Scanjet 4400c   03F0-0705
        Hewlett-Packard  Scanjet 4470c   03F0-0805
        Hewlett-Packard  Scanjet 3500C   03F0-2205
        Hewlett-Packard  Scanjet 3530c   03F0-2005
        Hewlett-Packard  Scanjet 3570c   03F0-2005
        This backend expects device names of the form:
        Where special is a path-name for the special device that corresponds to
        a  USB  scanner.   With  GNU/Linux systems, such a device name could be
        /dev/usb/scanner0 or /dev/usbscanner1, for example.


        The hp_rts88xx.conf file contains the device name  that  correspond  to
        the  hp44x0c  scanner.  Empty lines and lines starting with a hash mark
        (#) are ignored.
        A sample configuration file is shown below:
               # Comment
               /dev/usbscanner # option_CCD # CCD0 or CCD1  allowed  #  if  you
               receive a black image, change it to CCD1 option CCD0
        The  first  line  is ignored. The second line is the device filename to
        use in order to access the hp44x0c Scanner. If no device is given,  the
        backend will use libUSB.

               SANE_CONFIG_DIR below).

               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 config‐
               uration  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 sepa‐
               rator 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
