SANE Scanner Access Now Easy                          sane-u12(5)



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.


SUPORTED DEVICES
     The backend is  able  to  support  some  early  Plustek  USB
     scanner 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 I 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 dev-
     ice. If vendor- and product-id has not been  specified,  the
     backend 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-
     scanner 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/sane/libsane-u12.a
          The static library implementing this backend.

     /usr/lib/sane/libsane-u12.so
          The shared library implementing this  backend  (present
          on systems that support dynamic loading).


ENVIRONMENT
     SANECONFIGDIR
          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  SANECONFIGDIR  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 verbos-
          ity of the output.

          Example:  export SANEDEBUGU12=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

     or directly from the projects' homepage at:
     http:/www.gjaeger.de/scanner/u12/

     To obtain debug messages from the backend,  please  set  the
     environment-variable   SANEDEBUGU12  before  calling  your
     favorite scan-frontend (i.e. xscanimage).
     i.e.: export SANEDEBUGU12=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.
