I couldn't find any information about USB 3 and SANE, but on my particular hardware it doesn't seem to be supported. My Epson Perfection V33 works fine when plugged into a USB 2 port, but when plugged into a USB 3 port it rarely works. I'm using the epkowa backend, and have attached a log. For all I know it could be the scanner itself doesn't support USB 3. Even though USB 3 is supposed to be backwards compatible, I understand it doesn't always work as advertised.
Thanks for any insight, Tom -------------- next part -------------- [sanei_debug] Setting debug level of dll to 128.
