I'm trying to unlock my Google Stadia controller with this procedure on my Windows 10 desktop PC (it doesn't have Bluetooth wireless).
I got as far as doing the four finger salute (Ellipses + Balloons button + A + Y) whilst the Stadia controller was plugged into my PC via USB3.
Now Chrome wants to reconnect to the controller but no longer sees it. Do I need a Bluetooth wireless adapter on my PC for the next steps to happen, i.e. to download and install new firmware?
The controller is definitely >10% charged (and I gave it an extra charge) otherwise you're prevented from even starting the procedure.
System requirements: Chrome 108 or newer. I'd check that. Watching a video on YouTube, when trying to connect through the Chrome device list again it says
The Stadia controller name could be ST Blank RT Family, Stadia Controller, or USB COMPOSITE DEVICEIt sounds like you're seeing none of those options?
