Hi,
my scanner works perfectly when I log in in as root. As an
unprivileged user, I just get this error message:
$ 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).
I ended up in a brute force attempt saying in /etc/devfs.conf:
perm * 0666
Still, this didn't work. Starting "truss" and "diff" relvealed the
following difference:
root:
open("/dev/ugen0.2",O_RDWR,00) ERR#6 'Device not configured'
open("/dev/ugen0.2",O_WRONLY,00) = 6 (0x6)
unprivileged user:
open("/dev/ugen0.2",O_RDWR,00) ERR#13 'Permission denied'
Even when saying something like
chmod 0666 /dev/ugen0.2
the permissions will be 0644 after the run of "scanimage -L".
Could somebody please enlighten me what's going on here? What did I miss
when installing Sane?
"pkg_info -Dx sane-backends" stays empty.
Thanks in advance.
Bertram
