Does anybody have a scanner that identifies as a Mustek 1200 CU (several scanners are this, under the hood), they they can try with the simple scan program?
On my Fedora 20 computer, running the Mate desktop, the scanner light goes out shortly after it does the little test dance, and it scans the rest of the page with no lamp on. Yet, if I plug the scanner into a very old Fedora release, or CentOS, it works normally.
It shouldn't scan unlit, there's no option for it, and it's not a scanner meant for scanning transparencies.
