Property	Modifier	Type	Description
`axes`	`readonly`	readonly `number`[]	MDN Reference
`buttons`	`readonly`	readonly `GamepadButton`[]	MDN Reference
`connected`	`readonly`	`boolean`	MDN Reference
`deviceType`	`readonly`	`number`	-
`id`	`readonly`	`string`	A string identifying the controller. When available (firmware 5.0.0+), this is the controller's device name plus its hardware serial number, e.g. `"Nintendo Switch Pro Controller (XAW10012345678)"`, making it stable and unique per physical controller. The serial is read from the `hid:sys` service and cached — it is only re-queried when a controller is connected or disconnected, never on the input-polling hot path. When the serial can't be obtained (older firmware, no serial, or a system error) `id` falls back to a unique-per-slot string of the form `"switch-gamepad-<index>"`.
