I then took a look at SlackBuilds. The Epson Perfection V30 is unfortunately not mentioned. I also noted that it states at the top:VueScan found an Epson Perfection V300, but no Epson software for this scanner was found on your system. Try downloading a driver for this scanner from http://www.avasys.jp/english.
This, despite there being listed a iscan-proprietary-drivers-2.10.0.1-1.3.x86_64.rpm file at the bottom of the page. I also noticed that for some reason, the .rpm files referred to are from OpenSuSE. The Avasys site has both source files as well as, .rpm and .deb packages for the Epson Perfection V30.These are the proprietary binary-only i386-only libraries for EPSON USB scanners.
At this point, I am a bit confused. Do I try to modify the SlackBuild script, do I build from the source provided from Avasys, or do I do something completely different?
