Cannot get gamepad input working. joystick.py example

[Christopher Lee Fanning]

Hello, 

I can't get joystick.py to work.

System is running Fedora 24.  Using a PS4 gamepad over BlueTooth. The gamepad works with the other pygame projects, but I'm trying to get it to work with Kivy.  I get a blank window and no buttons produce any response, 

Thanks in advance,

Chris

These kind of errors mean that you need to put yourself into the "input" group.

[Christopher Lee Fanning]

Hey,

Thanks for your reply.  I've added the user to the input group, and the errors are gone, but the gamepad's buttons are not being picked up by the app.

It looks like the kivy example is using the wrong device.

Here is a snippet from dmesg and the new output.
