Connection checklist
Most browser controller problems start before the test data arrives. Work through the simple checks first, then rerun the live input test.
- Connect the controller by USB for the first test, then compare Bluetooth or 2.4G later.
- Press any controller button after loading the page to wake the browser Gamepad API.
- Close games or launchers that may hold exclusive controller access.
- Try Chrome, Edge and Firefox if one browser does not expose the device correctly.
- Disconnect and reconnect the controller if the page still shows stale input.
Interpreting common results
A small stick center offset is normal. The important question is whether the offset is large enough to move a game character or camera when the stick is untouched.
If a trigger never reaches the full range, test slowly several times. If the value remains capped, the issue may be hardware wear, driver mapping or platform-specific behavior.
- Use stick drift for center noise.
- Use circularity for outer-gate travel.
- Use polling rate only for same-browser comparisons.
- Use vibration results as capability detection, not proof that the controller motor is broken.
