[sane-devel] ScanImage -L fails as user

[m. allan noah]

You will have to adjust the device permissions, using something like
udev, or hal. Unfortunately, the mechanism seems to change frequently
with linux distros, so I cannot be more specific. You can look in the
sane-backends package that came with the distro, and see what sort of
files it installs.
