DEVICE CONTROL DEVICE, CONTROL METHOD THEREOF, AND DEVICE CONTROL SYSTEM

PROBLEM TO BE SOLVED: To provide a device control device capable of remotely controlling an information processor on a network by using an internal device.SOLUTION: A device control device 20 sends virtual device identification information 204 for identifying an internal device 40 as a device for performing virtualization control to an information processor 10, and the device control device 20 relays data communication using USB data, which is performed with the internal device 40 while the information processor 10 performs virtualization control of the internal device 40 in accordance with the virtual device identification information 204, and further converts USB data to be relayed into a first data format to be used in data communication with the internal device 40 and a second data format to be used in data communication with the information processor 10.
