We could count aproximately how many scanners are broken NOW since SANE 1.0.27 by disabling Linux USB3 workaround by default vs how many scanners could be broken by setting SANE_USB_WORKAROUND=1
Currently scanning with lots of mainstream SAMSUNG and XEROX multifunctional printers doesn't work in Ubuntu 18.04 LTS, but they works with Ubuntu 16.04 LTS, so, this is a very important regression and this should be fixed ASAP. If enabling SANE_USB_WORKAROUND=1 by default couses problems with few new scanners, which didn't work in Ubuntu 16.04 then this isn't such big problem like now - it's easier to write in Ubuntu 18.04 LTS Release Notes - new USB3 scanners should add SANE_USB_WORKAROUND=0 to /etc/environment instead of cousing problems for users, who upgraded from 16.04 LTS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1741977 Title: Scanning fails with many Samsung multifunctions (SCX-3200, SCX-3400, CLX-6260) after upgrading to Ubuntu 17.10/18.04 (SANE_USB_WORKAROUND=1 needed) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1741977/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
