Mas scanimage -L não diz nenhum scanner.
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).
Então o que é que eu perdi? Eu tentei seguir o COMO FAZER, mas ele não está me dando nenhum insight com base nos conselhos de solução de problemas.
Isso é típico se o usuário que executa scanimage não tiver direitos de acesso ao dispositivo. Você pode verificar a qual grupo o dispositivo pertence usando:
ls -la /dev/bus/usb/002/004
(a parte 002/004 foi tirada da sua saída sane-find-scanner ) e verifique se o usuário saned é membro do grupo que possui o dispositivo. Certifique-se de reiniciar o daemon saned após essa alteração.
