I am trying to connect a wired Xbox 360 controller to my Samsung Galaxy Tab 2 10.1 tablet (running Samsung's stock Android 4.1.1 ROM) via. an OTG adapter. When I connect it, the following two messages appear: "High-power USB device connected." "Can not access to this device. "Connected device needs power supply." Due to this, USB/BT Joystick Centre can't detect the controller. Due to the poor English in the second message, I am presuming it's a Samsung ROM issue, rather than an Android/a tablet hardware issue. Any ideas?
