sane-u12(5) 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.
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.

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

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.
