Did you change anything since it worked? And I really mean anything,
even if you think it's absolutely unreleated to scanning (e.g.
connect or turn on a parallel printer). I don't think that you've
changed anything on the scanner (e.g. firmware). The scanner is
no longer identified with it's name because the software can no
longer talk to the scanner ("Illegal response ...").
