While the GTA01 and GTA02 can both operate as USB host, they boat are
NOT an OTG compliant USB OTG host and therefore doesn't have a OTG
compliant Mini-AB socket.

Please complain to Samsung for producing SoCs with such a lack of USB
functionality :)

OTG is more than the software stack, more than the hardware jack
mechanics and more than supplying power to the socket.  OTG has fairly
complex electrical level requirements, too.  Those have to be handled in
a OTG compliant USB transceiver chip.
