You got it working, but this information might still be interesting in case of future problems: The Android "driver" is very different from the one I wrote from scratch and upstreamed. The mainline driver is less lines of code (iirc 25%), less complicated (Android vibration support is spread over multiple drivers/arch code), more efficient (Android drivers does GPIO bitbanging instead of PWM) and provides more features (Android driver does not allow all strength settings). Also it uses normal input device API instead of a custom one. P.S.: Sorry, I don't have much time to work on D4 at the moment :( -- Sebastian
