Thanks to
Valentin Hilbig who wrote the ppic code, Kazuhiro Sasayama
who wrote the original SANE Epson backend and all people working for the SANE project,
Simone Fabris who helped me testing in the first hour, Norihiko Sawa, Wolfgang Wilms and all other I forgot to name here.
Oh, and
Epson
for building scanners. If they would come already with Linux drivers, they would be perfect.
