You may need to update or configure the controller - skip ahead to Set Up Your Controller Via The Xbox Accessories App. You will know if you were successful if the Xbox One controller power light goes solid. The Xbox One controller should hopefully appear in the list after a few seconds - choose to pair to it. From the screen that appears select "Bluetooth". However, connecting it through your computer can be difficult as it depends on what controller you’re using. If you’re one of the many who play on PC and enjoy using a controller to play, you’re in luck as Elden Ring has controller support.
There is a workaround - hit the + symbol next to "Add Bluetooth or other device" on the "Bluetooth and over devices Settings" page. Elden Ring is available for PlayStation, Xbox Series X/S, PC, and Steam Deck. However in our testing we struggled to get the PC to find the controller. The controller's power light should flash quicker, and then "Xbox Wireless Controller" should appear in the list of devices to connect to on the "Bluetooth and other devices Settings" page. In theory, you should be able to connect your Xbox One controller simply by pressing the power button, and then pressing the circular connection button on the top of the controller next to the Micro USB port. All you need to do is make sure that your PC's Bluetooth connection is on - Search for "Bluetooth and other devices Settings" from your Taskbar.
If you have the latest Xbox One controller designs with Bluetooth functionality and a PC or laptop with Bluetooth functionality, you don't need the Xbox Wireless Adapter to connect the Xbox One controller wirelessly.
