OTG is a supplement to the Hi-Speed USB (USB 2.0) specification that augments
existing USB peripherals by adding to these peripherals limited host capability to
support other targeted USB peripherals. It is primarily targeted at portable devices
because it addresses concerns related to such devices, such as a small connector
and low power. Non-portable devices (even standard hosts), nevertheless, can also
benefit from OTG features.
