udev isn't just for pluggable devices, packages can provide udev rules
to ensure that devices appear with a consistent name,
e.g. /dev/input/event[0-9] does not include only pluggable or external
devices, it can contain several internal input devices as HIDs but the
actual number is not predictable. To make sure the package reads from
the correct device, it is wiser to provide a udev rule which gives a
particularly identified input device (by classification / type /
interface or even vendor) a known /dev location as a name or symlink.
