Comment # 42 on bug 905034 from Johannes Meixner

I do no longer find any time to work on such issues
(neither help with debugging nor anything else).

In general see
https://en.opensuse.org/SDB:Configuring_Scanners
therein in particular the section about
"RPM packages of the 'sane-backends' scanner drivers"
that reads (excerpts):
---------------------------------------------------------------------------
In general we (i.e. openSUSE) distribute the "sane-backends" scanner
drivers from the SANE project but we do not develop scanner drivers.

Usually we do not have all those various kind of scanners for all those
various kind of scanner drivers so that usually we cannot do anything
when a particular scanner driver does not work. In particular usually
we cannot reproduce issues with scanner drivers.

When a particular scanner driver is listed at the SANE project
that it should work for your particular scanner model but it does
not work for you with the currently latest "sane-backends" version
that is officially released by the SANE project, then it is recommended
to report the issue directly to the driver authors at the SANE project
http://www.sane-project.org
so that there is a direct communication between you and the upstream
authors.
