USB On-The-Go

Every USB communications is between a host and a device. Devices can't communicate with each other directly. The On-The-Go supplement to the USB specification defines a new type of device that can function as both a device and as a scaled-back host (but not both at the same time). When functioning as a device, the On-The-Go device can communicate with a PC or other USB host. When functioning as a host, the device can connect to USB peripherals.
