[sane-devel] Sane no longer works

[Steve Cohen]

USB 2.0 vs. USB 3.0 makes no difference.  And talk about motherboards
doesn't seem like it's heading up the right tree, since the same computer
and motherboard used to work with xsane and this scanner.

At this point I feel like we're just trying this and that, and I'd like to
actually understand what's happened here.
