From 8338410ac761fb893fe28aecd9cbaa04e7782cdb Mon Sep 17 00:00:00 2001 From: Rodrigo Rivas Costa Date: Mon, 16 Apr 2018 14:27:02 +0200 Subject: UPSTREAM: HID: add driver for Valve Steam Controller There are two ways to connect the Steam Controller: directly to the USB or with the USB wireless adapter. Both methods are similar, but the wireless adapter can connect up to 4 devices at the same time. The wired device will appear as 3 interfaces: a virtual mouse, a virtual keyboard and a custom HID device. The wireless device will appear as 5 interfaces: a virtual keyboard and 4 custom HID devices, that will remain silent until a device is actually connected. The custom HID device has a report descriptor with all vendor specific usages, so the hid-generic is not very useful. In a PC/SteamBox Valve Steam Client provices a software translation by using hidraw and a creates a uinput virtual gamepad and XTest keyboard/mouse. This driver intercepts the hidraw usage, so it can get out of the way when the Steam Client is in use.
