Comment 31 for bug 1728012

I can confirm that the Epson Perfection 4490 Photo scanner, iscan-gt-x750-bundle-1.0.0.x64 based, works by creating symlinks of the /usr/lib/sane/libsane-epkowa* files into the /usr/lib/x86_64-linux-gnu/sane directory by issuing the command 'sudo ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-gnu/sane' as said above; no need to tinker with the udev rules files in my case. This doesn't look like a bug fix to me, it's a workaround, needing a user tweak, libsane1 should look for third party sane drivers (once called backends IIRC) in the "legacy" directories as well as in the new ones, for backward compatibility.
