Abstract: A storage device is operable to be coupled to a host electronic device. The storage device includes a memory operable to store an operating system, applications and to provide mass storage functionality, a processor operable to run the operating system and execute the applications on the storage device and an interface is operable to couple the storage device to the host electronic device. The interface provides a data communication path and a power communication path between the storage device and the host electronic device. The storage device has a master storage device mode in which the storage device is operable to control at least one slave function of the host electronic device and a slave storage device mode in which at least one slave function of the storage device is controlled by the host electronic device.
