The Nacon Revolution Unlimited controller doesn't work with Chrome on my Mac. The Xbox One S controller via Bluetooth does work.
Chrome/Stadia does see that a controller is connected (keyboard button hints change into controller button hints) but it doesn't register any presses. (That's with the controller on PS4 mode. On Xinput mode, the controller isn't recognized at all, but that's normal for Mac.)
Interesting. Yes, every input works on that site, and it's correctly recognized as Revolution Unlimited Pro Controller (Vendor: 146b Product: 0d08). But it doesn't work in Stadia.
having this exact same issue with a razer raiju mobile, works great on the phone, but will not work on my pc or my chromebook through the chrome browser, though all the inputs do register
