sane-u12(5)						   SANE Scanner Access Now Easy 					       sane-u12(5)

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 scanner based their old parport design around the ASIC 98003 and other rebadged Plus- tek 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 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/lib64/sane/libsane-u12.a The static library implementing this backend. /usr/lib64/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. 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 configura- tion 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 explic- itly 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_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 SEE ALSO
sane(7), sane-usb(5), sane-plustek(5), /usr/share/doc/packages/sane-backends/u12/U12.changes http://www.gjaeger.de/scanner/u12/ 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 SANE_DEBUG_U12 before calling your favorite scan-frontend (i.e. xscanimage). i.e.: 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. 14 Jul 2008 sane-u12(5)
