One is the Google TV CC so unfortunately no USB-inputs. However the other is a USB-C dock mainly to be used with my Logitech Gcloud. So any BT-channel on the Pro 2 would work with the USB-adapter?
I’ve also been looking at newly release Gulikit KingKong Pro Max 3. It has several BT-channels plus one 2.4GHz with the included USB-adapter that unfortunately only seem to support Windows. However, I’ve heard mixed reviews of the KKPM3 in regards to hardware-quality and latency.
Isn’t all the Playstation controllers since the Dualshock 3 D-input? Seems like that would be a common BT-controller on Android with lots of support.
