Well, last try ? I put up an HTML page
executing exactly the code I linked you before, the test is still the same : once the page is open, plug in the controller.
It's not exactly the same code as in the plugin. The plugin checks lots of thinks, like what browser it is, what gamepad, if it knows how to map it, ... (witch could explain that the sample capx didn't trigger anything, if C2 ignores unknown gamepads). The function I used is only here to tell if your controller is usable by the browser, if it's detected when plugged in.
