A PC controller setup is only as good as the path from the pad to the game. Before you tweak Steam Input or in-game binds, confirm the hardware in a browser with the PC Controller Tester or the general Controller Tester. Those pages use the Gamepad API to show live buttons and axes without installing a special desktop app. That makes them ideal for quick checks after you change cables, dongles, or Bluetooth adapters.
USB versus Bluetooth on Windows
- USB is usually the most reliable path for browser detection and rumble on Vibration.
- Bluetooth must finish OS pairing before any gamepad tester can list the device.
- Windows Game Bar and exclusive apps can confuse detection. Close them, reconnect, and press a button.
If the pad never appears, follow Controller Not Detected and verify presence on Controller Detection. Wired connections reduce latency and dropouts for competitive play. Wireless is fine for couch sessions once pairing is stable.
Xbox, PlayStation, and generic pads
Xbox pads on PC are often plug and play. DualSense and DualShock models usually work over USB in browsers; Bluetooth behavior depends on the Windows build and whether another app already claimed the device. Generic DirectInput pads may show as unknown mapping. That is normal: press each control and map by index instead of by Xbox names. After detection works, validate sticks with Stick Drift and center gates with Deadzone so you catch hardware issues early.
Browser honesty for PC testing
The browser does not call native XInput directly. It reads whatever the OS exposes to the Gamepad API. That is enough for a solid health check, but it will not replace vendor firmware tools or guarantee adaptive triggers and touchpad gestures. For the technical limits, read Gamepad API Explained.

A practical PC workflow
- Connect USB or complete Bluetooth pairing in Windows settings.
- Open the PC Controller Tester and press a button to wake the pad.
- Confirm every button, both sticks, and both triggers.
- Run stick drift and deadzone checks before ranked play.
- Only then configure Steam Input or game-specific remaps.
