From: Christopher Crockett <chaorace@xxxxxxxxx> An effort has been made to support every official model and firmware version I could track down info on. The following controllers _should_ have working paddles with this PR: - Xbox Elite (**untested**) - Xbox Elite Series 2 on early firmwares (**untested**) - Xbox Elite Series 2 on v4 firmwares (Tested v4.8.1908.0) - Xbox Elite Series 2 on v5 pre-BLE firmwares (**untested**) - Xbox Elite Series 2 on v5 post-BLE firmwares (Tested v5.13.3143.0) This patch also introduces correct handling for the Elite 1 controller and properly suppresses paddle inputs when using a custom profile slot. Starting in v5.11, certain inputs for the Elite 2 were moved to an extra packet that is not enabled by default. We must first manually enable this extra packet in order to correctly process paddle input data with these later firmwares.
