I'm trying to use Input.start_joy_vibration(0, 1, 1, 1) on an Xbox 360 controller but it is not working. I'm using Win10 and Godot 2.1.3.
Input.start_joy_vibration(0, 1, 1, 1)
Input.startjoyvibration(0, 1, 1, 1) works fine on my Linux machine with an original Xbox Controller S at least.
I don't have vibration also on a PC usb controller, windows 8.1, Godot 2.1.4
Searching here and in github issues I could not find out if it is a general bug or only happens for some controllers.
