What I was saying is I rather prefer a log-message that says
"libevdev: eventXY: <some_message>" than to require me to set
event-masks via env-vars. Because I usually prefer having as much
information as possible and filter afterwards, than having to redo
some testing because I didn't get enough information. Especially for
libevdev which is quite low-traffic debug messaging (or do we log each
received message?).

Anyhow, I really don't care much, so feel free to add either.
