README for libsane-extras
-------------------------
The libsane-extras package provides some SANE backends not yet included in the
regular SANE distribution.
Backends currently included in libsane-extras :
* epkowa
* geniusvp2
* hp_rts88xx
* hp3900
For an history of this package, see changelog.Debian.gz.
How to use the backends:
------------------------
The backends are automatically enabled when libsane-extras is installed. See
the libsane-extras file in /etc/sane.d/dll.d to enable or disable the backends
provided by this package. This file is similar to SANE's dll.conf file.
Edit the backend's configuration file, located in /etc/sane.d/, and named after
the backend.
About the epkowa backend
------------------------
The epkowa backend is a modified epson backend released by EPSON, with improved
support for some of the scanners supported by the epson backend.
You'll need to disable the epson backend in /etc/sane.d/dll.conf to use the
epkowa backend.
For some scanners, the epkowa backends relies on proprietary, binary-only
modules that are loaded at runtime if needed; those modules are of course NOT
provided in this Debian package, due to their obvious non-freeness. For the
affected scanners, the backend will simply fail to work. In addition to the
module, the firmware file for the scanner is also required.
The following scanners require the use of a proprietary module to work with
the epkowa backend:

You can download the module and firmware files from the Epson Avasys website at:
<http://www.avasys.jp/english/linux_e/index.html>
The module and firmware files are distributed in the form of an RPM package;
you'll need to install the rpm and cpio Debian package to extract the content
of the RPM file:
- rpm2cpio iscan-plugin-....rpm > foo.cpio
- cpio -i --make-directories --no-absolute-filenames < foo.cpio
The module and firmware files will be available in the usr/lib/iscan and
usr/share/iscan directories, relative to the current directory. You need
to copy the module files to /usr/lib/iscan and the firmware file to
/usr/share/iscan.
=> How to get a backend included in this package ?
--------------------------------------------------
File a bug with severity "wishlist" against the libsane-extras package, in the
Debian Bug Tracking System (BTS). See http://bugs.debian.org for more information
on how to file a bug.
Include a short description of the backend in your bug report, along with a URL
where more information can be found, and where the backend can be downloaded.
If all goes well, a new revision of the package will be rolled out a few days
later, including this new backend.
For any questions or suggestions, feel free to contact me.
