Comment 189 for bug 1728012

I understand why /usr/lib64/ doesn't work right now on Ubuntu (that's a directory commonly used by Fedora and Red Hat distros).

I don't understand why /usr/lib/sane/ doesn't work according to the comments here. When sane-backends was converted to multiarch, a patch was added that I think was supposed to enable /usr/lib/sane/ to still be supported.

If that patch worked, then maybe it makes sense to just add /usr/lib64/ there too.

I don't have a scanner myself to test any of this.
