SANE udev rules not working anymore
Linux kernel introduced new events for devices. My device is for example discovered on "bind" action which is not reflected in the sane's udev rules.
Quote from Lennart Poettering (systemd creator) on the line "ACTION!="add", GOTO="libsane_rules_end"" from sane udev rules:
"udev rules should be written in a style that a "change" event can be triggered any time, and the devices keep their properties. Writing rules that only set props on "add" are simply broken."
