Is there a standard set of tests to run?
Hi, Great to hear that the device works at least over ethernet. I am afraid I do not know (yet) how to solve USB issues, perhaps you can activate the sane USB debug environment variables (see the various sane-* man pages, "apropos" should show you them) and send the output of that when you try sane as root (maybe better than sudo for this test).
