USB OTG or just OTG is a specification that allows USB devices, such as tablets or smartphones to act as a host, allowing other USB devices such as USB flash drives, digital cameras, mice and keyboards to be attached to them. The use of USB OTG allows those devices to switch back and forth between the roles of host and device. A mobile phone may read from removable media as the host device, but present itself as a USB MassStorage Device when connected to a host computer.
