This is not the location of the regularly installed libsane package. You have installed something compiled from source as well. This is often a source of problems. Is there any particular reason you need to use this self-built version? The iscan package automatically enables the epkowa backend in one of /etc/sane.d/dll.conf or a file below /etc/sane.d/dll.d/. For Ubuntu 14.04 it would be the latter with a file name of `iscan`. The backend's configuration should be in /etc/sane.d/epkowa.conf. If you end up using the dll backend from /usr/local/lib/sane/ it will in all likelihood *not* read the configuration in /etc/sane.d/. You can copy the files installed by iscan to /usr/local/etc/sane.d. That ought to make things work but if you don't really need the self-built version I would get rid of it. >> Did you install the non-free plugin that is needed for the Perfection 3170? > > Yes see above, I'm not sure what you meant by non-free: the plugin is > available for download from epson.com It is non-free in the sense that the source is not made available. That takes away freedom 1: the right to study and change the program in source code form. For why this matters, have a look over at https://www.gnu.org/philosophy/ >> Is it found by the backend? > > how can I check this ? You can check by make the dll backend show which backends it is looking for where.
