A device is provided with a multicore microprocessor unit (21) capable of inter-processor communication, storage (22) for storing a file describing device configuration information, and a device interface (23). Threads of the microprocessor unit are separated: a first processor core drives the OS, and meanwhile, a second processor core drives the device driver for controlling the device interface. While sharing the device configuration information by inter-processor communication, a notification driver interface for notifying the operating system kernel of configuration information on the basis of the device configuration information is loaded and the second processor core controls the device connected to the device interface by reading a scenario sequence file into the notification driver.
