I have no idea what 'more-magic' xsane uses, as simple magic of root using scanimage isn't sufficient.
as your diff shows no success, only 'permission denied' the cause of the failure can't be identified ... maybe a 'export SANE_DEBUG_DLL=128' As user 'strace xsane 2>strace.user.log' As root 'strace xsane -L 2>strace.root.log' Finally 'diff strace.user.log strace.root.log' could be of help. Don't know. But it's worth a try, unless better ideas arise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1728012 Title: Many 3rd party scanner drivers are broken by a sane change To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1728012/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
