<p>To allow an electronic device to detect the connection of a device supporting a communication standard which the electronic device does not support. An electronic device (1) includes a communication connector (10), a determiner (21), and a setting controller (22). The communication connector (10) includes a power supply terminal (11) and a plurality of signal terminals (12a, 12b, ···). The determiner (21) determines whether a device connected via the communication connector (10) is a device capable of communicating according to a second communication standard, based on the potential of a predetermined signal terminal (12b) specified by a first communication standard but not specified by the second communication standard, among the signal terminals (12a, 12b, ···). The setting controller (22) switches the setting related to a power supply signal input from the power supply terminal (11), according to the determination result of the determiner (21).</p> |
