Use stat() to minimize input device opens when not using udev Calling open() on input devices can generate device I/O which blocks the main thread and causes dropped frames. Using stat() we can avoid opening anything unless /dev/input has changed since we last polled. We could have used something fancy like inotify, but it didn't seem worth the added complexity for this uncommon non-udev case.
