A communication control apparatus includes a first interface, a second interface, a determination unit, and a control unit. The first interface is connected to a detachable recording medium. The second interface is connected to an external device. The second interface includes a first bus controlled by a first bus controller and a second bus controlled by a second bus controller. The second bus has a maximum transfer rate less than that of the first bus. The determination unit is configured to determine a data transfer rate of the detachable recording medium when the detachable recording medium is connected to the first interface. The control unit is configured to establish a connection to the external device via the first bus when the determined data transfer rate exceeds a predetermined threshold, and via the second bus when the determined data transfer rate does not exceed the predetermined threshold.
