I created an ebuild for the proprietary firmware plugin for the Epson scanner GT-1500. Tested it with media-gfx/iscan-2.29.3.1 from bug #498524 Reproducible: Always
Created attachment 372532 [details] iscan-plugin-gt1500-2.2.0.1.ebuild Created ebuild based on media-gfx/iscan-plugin-gt-f500-1.0.0.1-r1 You need to dowload the file manually from Epson (Search for GT-1500): http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX
Btw: This scanner does not seem to work on USB3 ("Superspeed") ports. I saw other users reporting this issue. Use an USB2 port or otherwise it may not work as expected.
