What's the problem? Describe what went wrong.

Using a GameCube controller with the WiiU adapter doesn't work when trying to play netplay. Instead, Dolphin switches to what seems to be the default keyboard input layout.

What steps will reproduce the problem?

1. Select GameCube Adapter for Wii U for GameCube controller port 1
2. Restart Dolphin if necessary (to ensure the adapter is connected)
3. Start netplay, host a room (traversal or direct), and select any game
4. Start the game, a room by yourself is fine. The controller won't input anything, but the default keyboard input layout will be active.

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?

This bug was introduced in Dolphin version 8601. On the previous version, 8593, netplay works with the controller like normal. The relevant PR is here: https://github.com/dolphin-emu/dolphin/pull/3455

What are your PC specifications? (CPU, GPU, Operating System, more)

Bug occurs on both Windows and Arch Linux, across multiple hardware setups.

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
