I have added 3 more images. I own a Samsung SIII mini. Im sure you all know that it is not by default OTG enabled. I followed another thread and watched a Youtube video instruntion on how to make an OTG cable with power to the periferal. In my case a game controller. You will see that I took the whole OTG cable and connected everything in the Female usb shroud, this includes the pushbutton.
Hope you like.
