[sane-devel] USB 3.0 not supported?

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
