A peripheral for notifying a USB-connected upper apparatus of a device descriptor and allowing the upper apparatus to specify a communication partner destination by the function information shown in the device descriptor has: a peripheral function information holding unit which holds function information showing functions of the peripheral; a dependent peripheral function information holding unit which holds function information showing functions of a USB-connected dependent peripheral; and a USB control unit which reads out one of the function information held in those holding units by a selecting instruction and notifies the upper apparatus of the device descriptor in which the read-out function information is shown. A peripheral which can realize a multi-function without developing a dedicated driver and installing it into a PC is provided.
