What is the preferred way to determine when new devices become available as /dev/input/eventX?
Do I have to periodically examine the /dev/input directory, comparing my open files against the list of /dev/input/eventX devices, or is there a simpler way?
I have taken a brief look at hotplug.txt, but I think that would notify me of the underlying raw /dev/input device creation, and not necessarily the corresponding /dev/input/eventX creation.
You can use inotify.
Something like inotifywait -r -m /dev/input
