Connect and configure a Steam Controller

Gaming.

It's not a popular controller, but hey, if you have one, why not (try to) use it?

These steps are based upon the text on the Valve homepage yet slightly adjusted for clarification.

Firmware

1. Remove the batteries and plug your Steam Controller into your host computer using the micro USB cable.

2. Open Steam in Big Picture mode to receive firmware updates for the Steam Controller (this should happen automatically).

3. Disconnect the Steam Controller

Pair the Controller

1. Insert the wireless receiver into the front of your PC with clear line of sight to the controller.

2. Insert the batteries

3. Launch Big Picture Mode with your mouse and keyboard.

4. While in Big Picture Mode, select the Settings icon from the top right section of the client.

5. Settings / Controller Settings / Add Steam Controller

6. Follow the on-screen instructions

Controller Configuration

To apply configurations from the Community or to create your own, navigate to a game in your Library from Big Picture mode, then select Manage Game then Controller Configuration at the top.

This menu will only display when a controller is connected.

Ensure only one type of input is applied - Xinput (gamepad), or keyboard/mouse since hybrid input is rarely accepted by a game.
