Hello,
I recently got a pixel 9 and have installed graphene os on it with no issues so far. I stream games from my PC to my phone using Moonlight/Sunshine and have been using a Gamesir G8 USB-C based game pad controller. It worked fine on my old S22 and works fine on my wife's stock Pixel 9 pro. But it will not initialize at all when connecting to my phone running graphene os. I have updated the os to its latest version, I have turned off all the USB c exploit settings and enabled USB debugging. No luck. Has anyone else experienced this or have a solution to this? Thank you!
