Mini USB OTG Port Host/Device Connector (CN15)

USB On-The-Go, often abbreviated USB OTG, is a specification that allows USB
devices such as digital audio players or mobile phones to act as a host, allowing other
USB devices like a USB flash drive, mouse, or keyboard to be attached to them. Unlike
conventional USB systems, USB OTG systems can drop the hosting role and act as
normal USB devices when attached to another host.
