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 scannersbased 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

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 secondssane-backends 1.0.19Last change: 18 June 2004 1

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 loadedcorrectly 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). ENVIRONMENTSANE_CONFIG_DIR
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 thedirectory separator character, then the default direc-
tories are searched after the explicitly specifieddirectories. 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 forthis backend. Higher debug levels increase the verbos-
ity of the output.Example: export SANE_DEBUG_U12=10

Please send any information and bug-reports to:
SANE Mailing List Additional info and hints can be obtained from ourMailing-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 theenvironment-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.ATTRIBUTES
