Patent ID: 8532976

Claim:
An information processing device including at least one computer processor operating to implement functional units, comprising: an assigning unit for assigning a unique internal identifier to each of a plurality of connection controllers connected to the information processing device via wire or wireless connection, the respective internal identifiers being used for identifying each of the connection controllers; an internal identifier displaying unit for displaying the respective internal identifiers assigned to each of the connection controllers; a change accepting unit for: (i) selectively defining, as a focused controller, one of the connection controllers on which a predetermined request operation is carried out, (ii) accepting an assignment change instruction to change the internal identifier of the focused controller initiated by a user of the focus controller, and (iii) informing the connection controller defined as the focused controller of being selected as the focused controller by issuing a command to the focus controller to change a light emission mode of a light emitting device located on the focus controller to indicate the selection; and an assignment changing unit for: (i) determining whether or not one of the internal identifiers assigned to another of the connection controllers is the same as the internal identifier of the assignment change instruction for changing the internal identifier of the focused controller; and (ii) if the determination is negative, then changing the internal identifier assigned to the focused controller to an accepted internal identifier according to the accepted assignment change instruction.
