Waiting for a controller
This controller does not report the standard layout, so the diagram stays idle. Every input still reads correctly in the panels below.
Plug it in over USB or pair it over Bluetooth, then press any button — browsers only reveal a pad once it sends input.

Let go of both sticks for a few seconds to measure drift.
Browsers hide a controller until it sends input, so press a button or nudge a stick after connecting. Bluetooth pads need to be paired in your system settings first, and a few wireless dongles only appear once the receiver is seated properly. Firefox, Chrome and Edge all work; Safari support is partial.
Drift is when a stick reports movement while you are not touching it. Release both sticks and watch the resting figures above. Under 0.05 is normal wear. A reading that climbs on its own, or sits above your deadzone, means the potentiometer or hall sensor is worn and games will creep without input.
The deadzone is the slack a game ignores around centre so small imperfections do not move your character. Raising it hides mild drift at the cost of fine aim. Use the slider to find the smallest value that keeps your resting dot inside the dashed circle.
