GC controller not detected in Unity 2021.1.25f (WinUSB v6.1.7600.16385)

[GuitarBro]

This looks perfect for my needs, however despite the GameCube Controller input actions showing in the bindings list, none of them seem to be performed. The same input actions do seem to be performed with other controllers.

Platform: Windows 10
Unity version: 2021.1.25f
Input System package version: 1.1.1
Zadig installed driver: WinUSB v6.1.7600.16385

Let me know if there's any other information that would be helpful, as I'd love to be able to support the Wii U GC adapter.

Hey, so I don't have access to a gc controller or the mayflash adapter anymore at the moment, but I just bought them and I'll be able to give you an update on the 10th (that's when the mayflash adapter comes in).

Also, does the input debugger show any input received when you use the controller during edit mode? It could be that you're polling against a controller that isn't plugged in.

[GuitarBro]

Thanks, no rush. Looks like the input debugger doesn't seem to list the controller as a supported device (so no input). Confirmed the controller works fine in Dolphin using the same driver setup so in theory it sounds like it should be able to be detected.

And just to confirm, the GameCubeController layout does show in the list:

If the input debugger window doesnt show the device listed under unsupported then there'd be no way for my layout to even register with it. I tried it this morning without the zadig drivers and it managed to find the driver (under windows 11, not sure if windows 10 is any different). What is the mayflash adapter model number, and did you make sure that adapter is on PC mode?

[GuitarBro]

Ah, is this ONLY for mayflash adapters? I was using the original Wii U adapter since I had verified it worked with the Zadig driver with Dolphin.

[popcron]

I see, yes the mayflash a specific HID and hardware ids, any information on the official adapter and I'd be able to add support for it with enough trial and error ;)

[GuitarBro]

Ah ok, well no problem, appreciate the help regardless. Consider it a feature request if you ever get around to it. 😉

Here's some information :)

VendorID = 0x057e;
ProductID = 0x0337;
The 37 bytes are like this:

8 bytes for each port starting at index 2
1st byte is: A, B, X, Y, Dpad Left, Dpad Right, Dpad Down, Dpad Up (in this order)
2nd byte is: Start, Z, R button, L button (in this order)
3rd byte is: grey stick X
4th byte is: grey stick Y
5th byte is: C stick X
6th byte is: C stick Y
7th byte is: Left trigger analog value
8th byte is: Right trigger analog value

This should be enough for me to create a small tryout adjustment, I'll post here a snippet for it to be tested and if it works ill update the hid matcher

[GuitarBro]

Awesome! I can give it a try and report back with my results.

[enfyy]

Turns out the official adapter doesn't really work like an actual HID device so Unity is not detecting it (at least not for me).
That makes this a bit more difficult. However, i got it to work using libusb : https://github.com/enfyy/com.nfysoft.gamecubecontroller
Its not 100% stable yet but you're welcome to give it a try @GuitarBro

[GuitarBro]

Oh interesting, I'll have to check out that repo. Thanks for the suggestion.

[popcron]

Here's some information :)

VendorID = 0x057e; ProductID = 0x0337; The 37 bytes are like this:

added! also brought the package dependency to a newer input system version (1.3.0)

[GuitarBro]

Great! I'll have to give it a try.

[GuitarBro]

An update: I do see the matching device, but unfortunately no input is registered when I map to the buttons. Doesn't show as an input device in the list.

I did also try out the repo @enfyy mentioned a while back (though it now seems to be a 404?) which I did actually have some success with (with the notable issue that any runs after the first one cause a libusb error message to appear as noted). I still have it pulled down locally, if it would be of any use to reference.

Edit: that repo only works AFTER launching Dolphin Emulator at least once apparently. So not really a viable solution, but perhaps on the right track?
