DSU client - Dolphin doesn't separate each pad motion input

[joao_shino]

Hi,

I'm developing a DSU server for Nintendo Switch controllers on Linux (joycond-cemuhook) and currently I'm adding support for multiple controllers.

If I run my DSU server and cemuhook's pad test via wine, each controller's motion data is correctly used on each port, so it seems like the server itself is working fine.

On Dolphin, it lists the correct number of "DSUClient/X/Generic Gamepad" inputs, but if there's more than one controller it captures all controllers' motion (from all DSU controllers) and applies it to all Dolphin emulated wiimotes. So if there are 2 controllers and controller 2 is rotated, Dolphin applies this rotation to both controller 2 and controller 1.

I'm currently unable to test this with other devices or with other DSU servers.

I want to confirm if it's either:

• A Linux-only issue
• A DSU client implementation issue
• An issue on my DSU server

If the motion data is being correctly separated between the different controllers on the PadTest app (that counts as a DSU Client -- from the same author of the protocol itself), it's very likely to be a bug with Dolphin. Would you mind filling an issue report?

Hello, Can you make it for Android?? there is Motion Source(detected as Dualshock 4) it works perfectly,,but i want to add more players and Motion Source doesnt have option to Connect as 2nd Player or as extention motion input,, so i think if you port it to android it could be possible because it detects as different device(Generic Gamepad) .it would be awesome if it could be ported to android ,,and sorry for my bad english
