Comment 24 for bug 1741977

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
