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

CONFIGURATION
To use your scanner with this backend, you need at least two entries in the configuration file @CONFIGDIR@/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
- @CONFIGDIR@/u12.conf
- The backend configuration file
- @LIBDIR@/libsane-u12.a
- The static library implementing this backend.
- @LIBDIR@/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 configuration file is searched in two default directories: first, the current working directory (".") and then in @CONFIGDIR@. 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 "@CONFIGDIR@" 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

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.
