Trying to use joystick - Can't see/access /dev/input/js0 on RPi3
I am using the Joystick package (which I am also now maintaining) to connect to a USB joystick. I have no issues when I am on my Linux machine, but I have not been successful with the same code on a Raspberry Pi 3.
When I plug the joystick into my desktop and execute ls /dev/input, there are two additional results (compared to before plugging it in), event16 and js0.
With the RPi3, I only see an additional event1, but there is no js0, which is the device the code will try to open. Does anyone know how I can get js0 to become available?
Apologies if my terminology is all over the place. This is a little more low-level than I’m used to.
Thanks in advance!

If this is on nerves I think you might want to take a look at input_event:

Oh, that looks perfect! I needed to know about keyboard input too, so you just solved TWO of my problems. Thanks!
