Claim Text:
1. A communication control apparatus comprising: a plurality of interfaces each including a first bus controlled by a first bus controller and a second bus controlled by a second bus controller, the second bus having a maximum transfer rate less than that of the first bus, wherein a communication performed via the first bus and a communication performed via the second bus are controlled independently; a control unit configured to establish a communication link with a reading device via the first bus; and a determination unit configured to determine a data transfer rate of a detachable recording medium connected to the reading device in a case where the reading device including a first interface to be connected to the detachable recording medium and a second interface including a first bus and a second bus is connected to any of the interfaces of the communication control apparatus, wherein, in a case where the reading device is connected to any of the interfaces of the communication control apparatus, the first bus of the second interface of the reading device is connected to the first bus of the interface of the communication control apparatus, and the second bus of the second interface of the reading device is connected to the second bus of the interface of the communication control apparatus, wherein each of the first interface and the second interface complies with a different standard from each other, wherein, in a case where the data transfer rate of the detachable recording medium connected to the reading device determined by the determination unit exceeds a predetermined threshold, the control unit maintains the communication link with the reading device via the first bus, and wherein, in a case where the data transfer rate of the detachable recording medium connected to the reading device determined by the determination unit does not exceed the predetermined threshold, the control unit disconnects the communication link with the reading device via the first bus, receives a notification, which indicates that it is possible to establish a communication link via the first bus, transmitted from the reading device after the disconnection is completed, and establishes, by not responding to the notification, a communication link with the reading device via the second bus.
