Estou tentando fazer com que o scanner Epson Perfection V39 funcione no Arch. É um scanner USB e recebe energia diretamente da porta USB.
% sane-find-scanner
found USB scanner (vendor=0x04b8 [EPSON], product=0x013d [Epson Perfection V39]) at libusb:001:002
Tentando digitalizar:
% scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
