SANE Scanner Access Now Easy                      sane-genesys(5)



NAME
     sane-genesys - SANE backend for GL646 and  GL841  based  USB
     flatbed scanners

DESCRIPTION
     The sane-genesys library implements a SANE  (Scanner  Access
     Now  Easy)  backend  that  provides  access  to  USB flatbed
     scanners based on the Genesys GL646  and  GL841  chips.   At
     present,  the following scanners are known to work with this
     backend:

          Medion MD6228
          Medion MD6274
          Hewlett-Packard HP2300C
          Canon LiDE 35/40/50/60


     This is stable software for supported  models.  But  if  you
     test  new  or  untested  scanners,  keep  your  hand  at the
     scanner's plug and unplug it, if the head bumps at  the  end
     of the scan area.

     If you own a scanner other than the ones listed  above  that
     works  with this backend, please let me 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  the  sane-devel  mailing  list.  Even  if   the
     scanner's  name  is  only slightly different from the models
     mentioned above, please let me know.

     If you own a scanner that  isn't  detected  by  the  genesys
     backend but has a GL646 or GL841 chipset, you can try to add
     it to the backend.

SYSTEM ISSUES
     This backend needs  libusb-0.1.6  or  later  installed,  and
     hasn't  tested  in  other  configuration than a linux kernel
     2.6.9 or higher. However, it should  work  any  system  with
     libusb  where  the SANE package can be compiled. For setting
     permissions and general USB information look at sane-usb(5).



CONFIGURATION
     The contents of the genesys.conf file is a list of usb lines
     containing  vendor  and  product  ids that correspond to USB
     scanners. The file can also  contain  option  lines.   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 genesys.conf.
     "vendor_id" and "product_id" are  hexadecimal  numbers  that
     identify the scanner.

FILES
     /etc/sane.d/genesys.conf
          The backend configuration file (see also description of
          SANE_CONFIG_DIR below).

     /usr/lib/sane/libsane-genesys.a
          The static library implementing this backend.

     /usr/lib/sane/libsane-genesys.so
          The shared library implementing this  backend  (present
          on systems that support dynamic loading).

ENVIRONMENT
     SANE_CONFIG_DIR
          This environment variable specifies the list of  direc-
          tories  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  direc-
          tories  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).

     SANE_DEBUG_GENESYS
          If the library was compiled with debug support enabled,
          this  environment variable controls the debug level for
          this backend.  Higher debug levels increase the verbos-
          ity  of  the  output. If the debug level is set to 1 or
          higher, some debug options become  available  that  are
          normally hidden. Handle them with care. This will print
          messages related to core genesys functions.

     SANE_DEBUG_GENESYS_GL646
          This environment variable controls the debug level  for
          the specific GL646 code part.

     SANE_DEBUG_GENESYS_GL841
          This environment variable controls the debug level  for
          the specific GL841 code part.


          Example (full and highly verbose output for gl646):
          export SANE_DEBUG_GENESYS=255
          export SANE_DEBUG_GENESYS_GL646=255
