Christopher, "Theor, did this problem not occur for you personally (not someone else on another report of forum) in a release prior to Trusty?" The previous releases were not LTS and I wouldn't use them natively, so I can't tell. It used to work with 12.04LTS though.
I notice that some people claim it works if they switch from an USB3 to an USB2 port. As mentionned in the first post, I did try that and it didn't change anything, so I doubt this is the root cause. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1312594 Title: 04e8:3441 14.04 won't scan via Samsung SCX-3200 Multi-Function Printer Status in “sane-backends” package in Ubuntu: Incomplete Bug description: My multifunction Samsung SCX3200 printer is not detected by sane, but printing is fine.
