Multiple issues were reported upstream regarding USB 3.0. In some cases this was power management related (placing a USB hub in between the system and the scanner).

If this is still reproducible (preferably with version 1.1.1-4 in jammy), then please reopen. ** Changed in: sane-backends (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1395271 Title: USB 1 and USB 2 scanners fail when connected to USB 3 ports To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1395271/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
