Re: epson L210 scan
Dne 13.7.2016 v 13:51 Curt napsal(a):
Isn't there a way of getting more verbose output out of 'scanimage -L'
(like debugging info)?
it is not much
The man page for sane talks about setting certain environement variables.
this might be helpful:
export SANE_DEBUG_DLL=100
:~$ scanimage -vvvL

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).
Calling sane_exit
[dll] sane_exit: exiting
[dll] sane_exit: calling backend `epson2's exit function
[dll] sane_exit: calling backend `ls5000's exit function
[dll] sane_exit: calling backend `hpaio's exit function
[dll] sane_exit: finished
scanimage: finished
The other env variables I dont know ho to exactly use, according to man
sane:
set environment variables SANE_DEBUG_DLL, SANE_DEBUG_MUSTEK,
and SANE_DEBUG_SANEI_SCSI to 128 and then invoke scanimage -L .
