To begin using your mouse and keyboard on your Xbox console, all you need to do is plug these devices into an available USB-Type A port on your console.
Although the keyboard will work without any additional configuration, your mouse will require a few more steps to appropriately set up.
To configure your mouse:
- Press the Xbox button on your controller to open the guide.
- Select Profile & system > Settings > Devices & connections.
- Select Mouse. You'll see options for pointer speed and for swapping primary and secondary mouse buttons.
