After plugging in the Xbox Adaptive Controller, You should download the Xbox Accessories App off of the Microsoft Store in order to create custom button programs for the controller. You can have multiple profiles, with the position of the LED on the controller denoting which profile is active at any given time.
You can emulate any gamepad using this, however it’s highly recommended to use this in conjunction with WalkinVR for greater VR customization. Set the Right Stick Up and Down to your Desired Adpative Controller accessories within the Xbox Accessories application. This will represent standing and crouching respectively.
Do you have SteamVR Base Stations 1.0 or 2.0?
