Hi Unity forums,
I am trying to read the input of a logitech g29 shifter in unity. This used to work when used with the unity g29 wheel. But I am using a different wheel now so I needed a different way to hook up the shifter via usb directly to pc.
I purchased this device from amazon: https://www.amazon.nl/-/en/dp/B096S8D2RV/
It gives me this as device description:
In the windows dialog it is recognized and seems to pick up all the input correctly.
Can I get this to work somehow? Or do I have to forge my own connector using an arduino/teensy/microcontroller device? (like this video does
)
Thanks in advance for any input on the issue!
And if you use https://gamepad-tester.com/ how does it see it on windows? as HID device or as XInput?

Hi dmytro,
The unsupported device option in input debugger doesn’t do anything since I have not specified any devices in the input settings. And I cannot select the device there. Unity also does not find this device when listening for inputs in an action map/action.
When enabling ‘enable event diagnostics’ I get the following error only when the diy shifter is plugged in:
Seems the bug is in our native code not parsing the hid report correctly. Hard to say what exactly without having the device
Maybe try finding out how does HID device descriptor looks like, maybe this tool USB Device Tree Viewer will do, just copy paste it output for the device somewhere accessible.

I have the output of usbtreeview here:

That seems one for your keyboard.

@dmytro_at_unity Any more thoughts on this? Otherwise I am going to use a teensy to engineer something myself.
Sorry, don’t have much capacity right now. It seems somehow reports are empty, probably some issues either in how we parse hid report from windows in native code, or device is not usb hid compliant.
Feel free to report a bug though (help → report bug), so we will keep track about it, and hopefully get around fixing it when we get to racing wheel support proper.
Help, I bought an adapter for my g29 shifter because I use it with another wheel and the shifter doesn’t detect me, with usb treet viewer I got this text:[2-11]: Prolific PL2303GT USB Serial COM Port (COM3)
This is how it detects me but the description is:
