WHAT THE PAGE CAN READ

Browser limits

The tester can only display data that the operating system exposes through the standard Gamepad API. A controller can work in a console or native game while remaining invisible to a browser.

  • This page cannot pair Bluetooth or install USB drivers.
  • Some browsers require user interaction first.
  • Vibration support is separate from button detection.
  • Driver and Steam mappings can change button labels.
DETECTION FAQ

Still stuck?

Why does a browser need a button press?+

Browsers commonly expose a connected gamepad after the user interacts with it. Press a face button or move a stick after connecting.

Should I close Steam?+

Steam Input and other controller tools can change mappings or hold the device. Close them temporarily when diagnosing a browser detection issue.
