Upgraded from 16.04 to 18.04. Got a new Canon LiDE 220 scanner (because it's supposed to be completely supported). lsusb sees it at the right address (04a9:190f as device 027 on bus 001). sane-find-scanner doesn't see it. None of the various workarounds I've found (symbolic link & udev rules) makes any difference. Is there a way to point sane to the specific bus/device?
