NAME

   sane-u12 - SANE backend for Plustek USB flatbed scanners, based on older parport designs

DESCRIPTION

   The  sane-u12 library implements a SANE (Scanner Access Now Easy) backend that provides access to USB flatbed scanners based on Plusteks' ASIC 98003 (parallel-port ASIC) and a GeneSys
   Logics' USB-parport bridge chip.

SUPPORTED DEVICES

   The backend is able to support some early Plustek USB scanners that based their old parport design around the ASIC 98003 and other rebadged Plustek devices. The following tables  will
   give you a short overview.

   If your Plustek scanner has another Product ID, then the device is NOT supported by this backend.

   Vendor Plustek - ID: 0x07B3
   ----------------------------------------------------------
   Model:                   Vendor-ID:       Product-ID:
   ----------------------------------------------------------
   OpticPro U12             0x07B3           0x0001
   OpticPro U1212           0x07B3           0x0001
   OpticPro UT12            0x07B3           0x0001

   Vendor KYE/Genius

   USB Model:               Vendor-ID:       Product-ID:
   --------------------------------------------------------
   ColorPage Vivid III USB  0x07B3           0x0001
   ColorPage HR6 V1         0x0458           0x2004

CONFIGURATION

   To use your scanner with this backend, you need at least two entries in the configuration file /etc/sane.d/u12.conf

          [usb] vendor-id product-id
          device /dev/usbscanner

   [usb]  tells the backend, that the following devicename (here /dev/usbscanner) has to be interpreted as USB scanner device. If vendor- and product-id has not been specified, the back
   end tries to detect this by its own. If device is set to auto then the next matching device is used.

   The Options:

   option warmup t
          t specifies the warmup period in seconds

   option lampOff t
          t is the time in seconds for switching off the lamps in standby mode

   option lOffonEnd b
          b specifies the behaviour when closing the backend, 1 --> switch lamps off, 0 --> do not change lamp status

   See the u12.conf file for examples.

   Note: You have to make sure, that the USB subsystem is loaded correctly and you have access to the device-node. For more details see sane-usb(5) manpage. You might use sane-find-scan
   ner(1) to check that you have access to your device.

   Note:
   If there's no configuration file, the backend defaults to device auto

FILES

   /etc/sane.d/u12.conf
          The backend configuration file

   /usr/lib/x86_64-linux-gnu/sane/libsane-u12.a
          The static library implementing this backend.

   /usr/lib/x86_64-linux-gnu/sane/libsane-u12.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 directories that may contain the configuration file.  On *NIX systems, 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 direc
          tory (".") 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 or
          der).

   SANE_DEBUG_U12
          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_U12=10

CONTACT AND BUG-REPORTS

   Please send any information and bug-reports to:
   SANE Mailing List

   Additional info and hints can be obtained from our mailing-List archive at: http://www.sane-project.org/mailing-lists.html.

   To obtain debug messages from the backend, please set the environment-variable SANE_DEBUG_U12 before calling your favorite SANE frontend (e.g.  xscanimage(1)):

   export SANE_DEBUG_U12=20 ; xscanimage

   The value controls the verbosity of the backend.

KNOWN BUGS & RESTRICTIONS

   * The driver is in alpha state, so please don't expect too much!!!

   * When using libusb, it might be, that the backend hangs.  In that case, reconnect the scanner.
