sane-u12 - SANE backend for Plustek USB flatbed scanners, based on
|
|
older parport designs
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-u12</B> library implements a SANE (Scanner Access Now Easy) back-
|
|
end that provides access to USB flatbed scanners based on Plusteks'
|
|
ASIC 98003 (parallel-port ASIC) and a GeneSys Logics' USB-parport
|
|
bridge chip.
|
|
|
|
|
|
</PRE>
|
|
<H2>SUPPORTED DEVICES</H2><PRE>
|
|
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 <B>NOT</B>
|
|
supported by this backend.

|
<H2>CONFIGURATION</H2><PRE>
|
|
To use your scanner with this backend, you need at least two entries in
|
|
the configuration file
|
|
<I>/usr/local/etc/sane.d/u12.conf</I>
|
|
|
|
<I>[usb]</I> <I>vendor-id</I> <I>product-id</I>
|
|
|
|
<I>device</I> <I>/dev/usbscanner</I>
|
|
|
|
<I>[usb]</I> tells the backend, that the following devicename (here <I>/dev/usb-</I>
|
|
<I>scanner</I> ) 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 ist set to <I>auto</I>
|
|
then the next matching device is used.
|
|
|
|
<B>The</B> <B>Options:</B>
|
|
|
|
option warmup t
|
|
<I>t</I> specifies the warmup period in seconds
|
|
|
|
option lampOff t
|
|
<I>t</I> is the time in seconds for switching off the lamps in standby
|
|
mode
|
|
|
|
option lOffonEnd b
|
|
<I>b</I> specifies the behaviour when closing the backend, 1 --> switch
|
|
lamps off, 0 --> do not change lamp status
|
|
|
|
See the u12.conf file for examples.
|
|
|
|
<B>Note:</B>
|
|
You have to make sure, that the USB subsystem is loaded correctly and
|
|
you have access to the device-node. For more details see <B>sane-usb</B> <B>(5)</B>
|
|
manpage. You might use <B>sane-find-scanner</B> to check that you have access
|
|
to your device.
|
|
|
|
<B>Note:</B>
|
|
If there's no configuration file, the backend defaults to <B>device</B> <B>auto</B>

<H2>FILES</H2><PRE>
|
|
<I>/usr/local/etc/sane.d/u12.conf</I>
|
|
The backend configuration file
|
|
|
|
<I>/usr/local/lib/sane/libsane-u12.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-u12.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_CONFIG_DIR</B>
|
|
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 config-
|
|
uration file is searched in two default directories: first, the
|
|
current working directory (".") and then in
|
|
/usr/local/etc/sane.d. If the value of the environment variable
|
|
ends with the directory separator character, then the default
|
|
directories are searched after the explicitly specified directo-
|
|
ries. For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:"
|
|
would result in directories "tmp/config", ".", and
|
|
"/usr/local/etc/sane.d" being searched (in this order).
|
|
|
|
<B>SANE_DEBUG_U12</B>
|
|
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

<H2>CONTACT AND BUG-REPORTS</H2><PRE>
|
|
Please send any information and bug-reports to:
|
|
<B>SANE</B> <B>Mailing</B> <B>List</B>
|
|
|
|
Additional info and hints can be obtained from our
|
|
Mailing-List archive at:
|
|
<B>http://www.sane-project.org/mailing-lists.html</B>
|
|
|
|
or directly from the projects' homepage at:
|
|
<B>http://www.gjaeger.de/scanner/u12.html</B>
|
|
|
|
To obtain debug messages from the backend, please set the environment-
|
|
variable <I>SANE</I><B>_</B><I>DEBUG</I><B>_</B><I>U12</I> before calling your favorite scan-frontend
|
|
(i.e. xscanimage).
|
|
<B>i.e.:</B> <B>export</B> <B>SANE_DEBUG_U12=20</B> <B>;</B> <B>xscanimage</B>
|
|
|
|
The value controls the verbosity of the backend.

|
|
<H2>KNOWN BUGS & RESTRICTIONS</H2><PRE>
|
|
* 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.
