With latest pkgsrc it even works on sparc64 again ;-)

I tried to get the non-libusb (i.e. uscanner0) version to work with latest
sane-backends, but failed.

So I support removal of uscanner* (commenting it out) from all GENERIC
kernels.

Instead we should improve our device ownership handling in a  more
general way. Jared suggested dynamic groups (i.e. the kernel magically
adding the owner of /dev/console to a special group "consoleuser" or
something similar), but there are other alternatives.
