[sane-devel] Acer ScanWit 2720S

Hello Sane-devel,
dear Henning,

I'm digging out that old thread because I try to make the scanner
work. Max Ushakov is out of the game since he's working digital only
now.

Henning, on 23.10.2005 you were giving a hint how to compile the
sources, I did the following on sane-backends-1.0.19:

- Edit configure.in, add scanwit in the "BACKENDS="-section, run
"autoconf".
- patching the backend/Makefile.in like this, did it manually but this
in a patchfile might work (my naive idea how to alter a patchfile ...)

- copied the other files to backend/ directory.
- ./configure, make

Now I would like to leave my sane installation as is and just add the
scanwit drivers as described here
http://sourceforge.net/forum/message.php?msg_id=4250316 but with
scanwit-stuff. Will that work or doesn't sane know the scanwit because
it is somewhere else introduced to sane?

What would be necessary to include the driver in the supported
backends? Only the docs or fiddling with the scsi-stuff? I could write
something as a doc but I think programming is much beyond my
programmer-skills.

Thanks for hints!
