OTG MODE
Using the correct cables is the key to OTG operation. Testing was done using two cables joined together to create an OTG cable. An OTG cable has a micro A connector on one end and a micro B connector on the other end. The micro A connector is the host side of the cable and the micro B connector is the device side by default.
