I'm not the author of that backend so I may be completely wrong...
However, this time you get a completely different error. Openeing the
scanner works, but starting the scan doesn't:

There is no tranfer to the scanner involved at all. Looks like a
backend bug. It sets widths and height to 0 by default.
Try again with scanimage but set width and height explicitely to e.g.
10 mm (see scanimage --help for details).
