PROBLEM TO BE SOLVED: To provide a radio receiver and a computer program that suppress radio noise generated by USB communication.SOLUTION: A USB controller 112 circularly scans an end point descriptor (ED) registered with a non-periodic transfer list, and if a transfer descriptor (TD) is cued in at the ED, performs non-periodic transfer indicated by the TD. When a radio receiver 101 is outputting voice received from FM broadcast, if an execution period of non-periodic transfer performed according to the non-periodic transfer list is shorter than a prescribed period, a USB driver 2011 (a) adds a dummy ED to the non-periodic transfer list and (b) extends an execution period of non-periodic transfer, and thereby suppresses the average power of undesired electromagnetic radiation by non-periodic transfer such that it will become a level at which radio noise is not generated. |
