Okay, so scanimage is trying to load the epkowa backend but for some
reason cannot find the backend.

You probably have a /etc/sane/dll.d/epkowa.conf that adds it to the list
of backends to use. Otherwise, scanimage wouldn't try to load it.

This (libsane-epkowa.so.1) is the file I would have expected to be loaded.
I am clueless as to why this is not getting loaded so let's crank up the
debugging level for the dll backend. The following command is going to
fail as before but I want to see what the dll backend is doing when it
is looking for the epkowa backend, so
sudo SANE_DEBUG_DLL=127 scanimage -L 2>&1 | tee log
# If there's a lot of output, please attach the log file instead of
# pasting the output into your reply.

Your epkowa.conf looks fine.

Now apart from providing more information, you can try to "force" the
dll backend to find the epkowa backend with
$ sudo LD_LIBRARY_PATH=/usr/lib:/usr/lib/sane SANE_DEBUG_DLL=127 scanimage -L 2>&1 | tee log2
Please attach the log2 file.
Hope this helps,
