ABSTRACT:
A peripheral device is connected to a host device by a transmission path according to a predetermined interface standard to be communicable with the host device, and operates with power supply received from the host device through the transmission path. The peripheral device includes a main operation unit and a control unit. The main operation unit uses, in the operation thereof, non-standard current higher than an upper limit current value specified by the interface standard. The control unit operates in a standard power mode, which consumes current not exceeding the upper limit current value specified by the interface standard, to send the host device information indicating the use of the non-standard current, and performs, upon receipt from the host device of permission to use an extended power mode, which consumes the non-standard current, a process of activating the operation of the main operation unit in the extended power mode.
