If you think it should be removed, i can do that.

you are fully qualifying blink::WebGamepads, so I don't think you need these
(and it doesn't look like you use blink::WebGamepad at all in this file).

[Ted C, 2014/04/16 23:36:53]

polling_thread_ is a private class variable in gamepad_provider.cc, so I don't
think you should reference it here.

Maybe just say runs on the background polling thread.

And this comment doesn't really seem necessary to me.  It seems more an
implementation description than when this should be used.  I'd probably just
drop it.

is_paused or just paused to match the overridden method signature

I think you can remove this variable now?

[Ted C, 2014/04/16 23:36:53]

this doesn't look used in the implementation
