Hi there, the Google Daydream kit I have lying idly around here is incompatible with my Android phone. Yet the controller features some very nice hardware - a touchpad, some buttons, magnetometer, accelerometer, gyroscope: https://xinreality.com/wiki/Daydream_Controller And the protocol has been properly reverse engineered in https://hackernoon.com/how-i-hacked-google-daydream-controller-c4619ef318e4 So a proper driver isn't far away. But how to map the device's buttons and axes? A (possibly too) brief dive into the kernel source didn't come up with a proper role model. There appears to be no existing driver for "vr controller" type of hardware similar to the Daydream / Oculus / Vive controllers. Those seem to be supported in various userspace libraries. There are generic gyroscope sensor drivers all over the place in the kernel, but not specifically for a vr controller device. And there are spatial movement data mapped to an axis in hid-sony, hid-steam and hid-wiimote. So what is the proper way forward? I currently assume that the device should be mapped like a gamepad with the touchpad being an analog x/y axis. Is that correct? But it's frightening to decide things for the "first" vr controller driver and I currently wonder if it's therefore better to forget this and leave handling this device in userspace code. Thanks for advice, Hanno
