Hi,
I am trying to setup sane to use a canon CanoScan 3200F and was
directed to ask my question here from the IRC channel. I am using a
rasberry pi zero running Raspbian GNU/Linux 11 (bullseye) lite. I
compiled sane from source. Output of scanimage --version:
scanimage (sane-backends) 1.0.32.227-5591; backend version 1.0.32.
My scanner is recognized by lsusb and sane-find-scanner -v -v also
shows the scanner but complains "Couldn't determine the type of the
USB chip". Unfortunately scanimage -L cannot identify any scanners.
Following a post on the cent-os forums that had similar issues that
were resolved by installing the yum package
sane-backends-drivers-scanners for the user in question I tried to
look into whether I have the required backend drivers. The sane
documentation lists the scanner as unsupported but says in the
comments: "Actually this scanner is supported by the experimental
cs3200f backend now".
I could not find any files in the backends folder of my clone of the
source code that contained the string cs3200f and I found an old bug
report from the sane-backends ubuntu package that seems to confirm my
fears about missing backends. It states: "However, the experimental
CVS wasn't transferred over when they [the sane project] moved from
CVS to git."
Attached to this post was an email exchange from 2013 where someone
from the sane dev team supplied a backup of the experimental backend
and suggested a patch to /backend/Makefile.am and /configure.in to
allow its compilation.
Now this is where my attempts to resolve this myself kind of end. The
structure of the Makefile in question seems to have changed too
substantially since 2013 for someone with barely any C knowledge like
me to apply the relevant changes.
So, my questions: Am I even on the right track? Am I missing the
cs3200f backend with my "naked" sane install from source? If not is
there any other way to run the canon CanoScan 3200f with sane?
Very happy about any and all feedback.
Thank you and Best regards,
Dario Klenke
P.S.
this is the email exchange i mentioned earlier:

and this is the bug report from the ubuntu forums:

If you download the attachment here:
http://lists.alioth.debian.org/pipermail/sane-devel/attachments/20130327/d616faed/attachment-0001.bin,
...then rename the file to cs3200f.tar.gz you should find that it
contains the source you are looking for.
I will have a look at it later in the day but in the meantime you should
be able to check it out.
Cheers,
Ralph
