+ The most notable feature of USB OTG is support for a
+ "Dual-Role" device, which can act as either a device
+ or a host. The initial role is decided by the type of
+ plug inserted and can be changed later when two dual
+ role devices talk to each other.

+ Select this only if your board has Mini-AB/Micro-AB
