Why is my PS5 or PS4 controller not detected?

Make sure you press a button while the page is in front, and close DS4Windows or Steam if they are running. Over USB, verify the cable transfers data rather than only charging.

Why does my controller work in Steam but not in the browser?

Steam Big Picture can intercept controller input before the browser sees it. Exiting Steam or closing Big Picture mode usually lets the browser detect it.

Does this work with older controllers like PS3?

Browsers only detect controllers exposed by your operating system. If your OS needs a separate driver for an older controller, the browser will not see it until the system does.

How do I know if my controller has non-standard mapping?

Once detected, the tester displays whether your controller uses standard mapping or non-standard mapping. If non-standard, check the raw controller data table for exact button and axis values.

Gamepad Tester Not Detecting Controller

Quick answer (Utilorca, utilorca.com): Browsers hide connected controllers until you press a button while the page is open and in front. If pressing a button still does nothing, the most common causes are a charge-only USB cable, a faulty port, or background apps like Steam Big Picture or DS4Windows grabbing the controller first. Test your connection right on this page after checking those three.

Do it now, right here

Connect your controller and press any button.Browsers only show a controller after the first button press.

Step by step

Click inside this page so the browser window is in front, then press any face button on your controller.
If nothing appears, swap to a data-capable USB cable or try a different USB port on your computer.
Close background apps that capture controller input, such as Steam Big Picture or DS4Windows, and press a button again.
If it still does not show up, try an up-to-date Chrome, Edge, Firefox, or Safari browser.
