What's the problem? Describe what went wrong in few words.
GCPad no longer detects input from an external controller. In particular, PS3 controllers (as Input/0/PLAYSTATION(R)3 Controller) do not work, neither when connected via USB nor bluetooth.

What did you expect to happen instead?
In the GCPad configuration, button presses and analog stick movements should be displayed. In games, the game should respond to input.

What steps will reproduce the problem?
0. Connect a controller.

1. Verify it works correctly on Dolphin 4.0.
2. Open Dolphin 4.0-3382.
3. Open GCPad.
4. Select the controller from the device list.
5. Attempt to configure the controller.
6. GCPad doesn't detect any input.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Dolphin 4.0 works correctly
