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
