The first thing you need to do is stop making new threads for the same problem. You are getting mixed advise and fixing one thing but breaking another. Also the moderators will eventually call you on it.
You broke the selection code by changing ClavierSouri and Gamepad to zero, based on an earlier thread, but I had already fixed the logic to use the original values.
Also, you did not move the mouse code into the Keyboard group, so that it only runs when the correct controller is picked.
