disabling ppdev didn't help in my case. On my canon LiDE25 9plustek, it does let e get a preview scan (as it would on occasion let me) but the scan head does not return all the way (also as would do when it would actually scan) and on a second scan attempt, it would do the ususal.
What specific command can I run, and where do I look do get strace results for comparison? -- Canon Lide25 (plustek backend) scanner does not scan via gui https://launchpad.net/bugs/85488 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
