I'm using Chrome (Version 19.0.1084.46). I enabled the Gamepad API in chrome://flags. I plugged in some game pads, but navigator.webkitGamepads is always an array of length 4 containing only undefined.

navigator.webkitGamepads
GamepadList
  0: undefined
  1: undefined
  2: undefined
  3: undefined
  length: 4
  __proto__: GamepadList

What do I need to do to test out using gamepads? I'm on Ubuntu Linux if that matters.
