Yes. It's always confusing when an Epson scanner ends up being used with the snapscan backend ;) How about we ask the vendors to embbed the config file in the scanner ? :P (and here, we can only realize that the whole scanning world is such a mess, that we might never find a good solution to handle everything...)
