This file is needed by some Genius scanners using the gt68xx
backend (you have to copy it to /usr/share/sane/gtk68xx,
creating the dir if its empty). I had a hard time extracting
it from the Windows drivers without having Windows installed
so I'm putting it here for other people to download. I don't
know if that is legal but legal or not the only people that
is going to use this file are the Linux Genius scanner
owners, so I think is moral to put it here.
You can download the file: Here.
