re #31, in my original bug report, I'd tentatively concluded this was an issue with USB3 and I note in your report you also have issues with USB3. For me, as I mentioned in #23, installing the updated sane backends pretty much fixed this problem for me on a USB3 root hub. It's still fairly temperamental though, the major annoyance being it seems to take 30s to a minute to start scanning.
Personally, I think the USB3 subsystem is as buggy as anything, particularly with slower devices. I have encountered numerous spurious messages emitted from the kernel and complete system lockups all related to USB regardless of the type of peripheral in use. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1250196 Title: sane plustek backend not working on USB 3 root hub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1250196/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
