3rd Party Joycon Compatibility

[macromorgan]

Is there a list of compatible 3rd party joycons? I tried some cheap ones I got from Five Below and they failed miserably (I assume there were many things missing in the hardware this driver expects).

[grego9]

I've tried some cheap joycons with no luck either. In my case, I can pair them as individual controllers, but they start to rumble non-stop.

[arieleoar]

Same here, system recognizes JoyCons as Pro controllers and S buttons doesn't works at all, even joycond doesn't work as it cannot pair correctly the devices. I'm using dkms module from nicman23 because if i use builtin hid-nintendo module from the kernel provided in ubuntu 22.10 it makes the system crash awfully.

Do you know where exactly we should file a bug for this as it is now directly provided in different linux distros?

I have a 3rd Party pro-controller, after apply following patch, it can work, and it was hacked from SDL

could you post a photo of your controller that works with the above patch? thank you

thank you. It's the shittiest controller I have ever seen 😄

[nlflint]

I have a 3rd Party pro-controller, after apply following patch, it can work, and it was hacked from SDL

<patch omitted>

I have a King Kong 2 controller (in nintendo switch mode) with the same ret=-110 problem in kernel (6.8.2). I tried your patch on kernel 6.8.2 but the first part of the patch didn't apply cleanly (part 2 and 3 did). I was able to patch part1 by hand though. I compiled one version without the mutex (it's gone in 6.8.2), then ran another compilation that brought the mutex back.

Both versions (mutex or not) seem to behave the same, but the controller still doesn't work. It got rid of the return error in dmesg when paired, but the controller still isn't recognized by apps like Steam, jstest, or yuzu.

[dietolive-tw]

the patch of kernel 6.8.x will be like this, hope it can help.

Excellent, with that patch, my Gulikit King Kong 2 (in switch mode, via bluetooth) is working now. Steam and Yuzu detect it and the controls are responding. The tester JSTest-gtk still doesn't detect it, but it doesn't matter.

[emiliopedrollo]

I also have a Gulikit KingKong2 but I'm not being able to properly connect it.

I'm trying to build a dkms module by extracting hid-nintendo.c from the kernal 6.8 source and pasting it on a clone of nicman32 repository, then apllying the patch from https://github.com/DanielOgorchock/linux/issues/40#issuecomment-2029009734.

I'm not sure if I should blacklist hid_nintendo from modprob or even if I can do it and still use the dkms version. Or maybe the problem isn't related to that at all. Or even if the whole copy into a dkms thing is a thing at all.

it should not be necessary if you keep the same name of the module, it will be considered an update and replace the official one.

[kiodo1981]

How can I use this patch onn ArchLinux? Any AUR package? The controller shows up, it's connected via bluetooth It's compatibile for Nintendo switch When I press any key, it doesn't do anything Thanks.
