Summary
You can connect a Scuf Vantage 2 controller to your PS5, contrary to common belief. To set it up wirelessly, first ensure your PS5 is on and navigate to Settings using your original PS5 controller. Go to Accessories, then General, and select Bluetooth. Place your Scuf controller on a flat surface and flip the switch on the bottom left to wireless mode. Hold down the PlayStation button on the Scuf until it flashes. Then, pick up your original PS5 controller and scroll down the Bluetooth menu to find and select 'Scuf controller.' Confirm the registration by selecting 'Yes.' Your Scuf controller should now appear as connected. The Scuf Vantage 2 also comes with a small key to adjust trigger sensitivity by inserting it into a tiny hole beneath the L2 and R2 buttons. Turning the key adjusts how quickly the triggers respond.
