May be related, my Canon Lide25 (plustek backend) scanner which worked in Edgy, does not scan using kooka or xsane/xscanimage. It "pretends" to scan, the scanner bar does not move or light up in the preview/final scan, and it produces a black scan.
I only have found a few other very recent instances of this problem in other distros, but no useful information https://alioth.debian.org/tracker/?group_id=30186&atid=410366&func=detail&aid=304367 http://www.nabble.com/canon-lide25---impossible-to-scan-via-a-graphical-frontend-t3129854.html -- Scanner 04a9:220e used works in Dapper and Edgy not Feisty https://launchpad.net/bugs/78205 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
