What's the problem? Describe what went wrong in few words.
The L and R triggers do not seem to work, at least in Super Mario Sunshine. Pressing either of them does absolutely nothing. Every other button does what it is meant to do. To test, I mapped the L trigger (which centres the camera) to a physical button and pressed it. The camera centered. I pressed the on-screen L trigger. Nothing happened.

What did you expect to happen instead?
The buttons should work.

What steps will reproduce the problem?

1. Load a game that uses L or R triggers
2. Try to use on-screen triggers
3. Nothing will happen
