Then step 602 is performed: send a confirmation signal, and after confirmation signal sends, whether detection control unit transmits a feedback signal.
As shown in Figure 3, when after unlatching first expansion bus interface 61, now confirm that module 635 can send confirmation signal, attempts linking up with the first expansion bus interface 61 and control module 80 executive signal; After confirmation signal sends, whether detection module 633 can detect has corresponding feedback signal to transmit from control module 80.If there is feedback signal to transmit, then perform step 603; Otherwise, then step 604 is performed.
Perform step 603: make expanding device come to link up with control module executive signal by the first expansion bus interface.
Suppose that control module 80 provides the first expansion bus 81, and when expanding device 60 also opens the first expansion bus interface 61, confirm that the confirmation signal that module 635 sends just is sent to control module 80 by the first expansion bus 81.After control module 80 receives the confirmation signal, control module 80 can send feedback signal, and feedback signal also can by the first expansion bus 81 to be back to expanding device 60; Once detection module 633 has detected that feedback signal transmits from control module 80, execution module 634 just can make expanding device 60 link up with control module 80 executive signal by performing the first expansion bus interface 61.
Perform step 604: open the second expansion bus interface.
Otherwise as shown in Figure 3, when control module 80 only provides the second expansion bus 82, even if open the first expansion bus interface 61, the confirmation signal that expanding device 60 sends also cannot be sent to control module 80; Therefore, if do not detect in the schedule time after confirmation signal sends, corresponding feedback signal produces, namely represent that control module 80 does not provide the first expansion bus 81, now, activation module 631 can close the first expansion bus interface 61, and open the second expansion bus interface 62, use and attempt being linked up by the second expansion bus interface 62 and control module 80 executive signal.
Perform step 605: send confirmation signal, and after confirmation signal sends, whether detection control unit produces a feedback signal.
In like manner, after the second expansion bus interface 62 is opened, confirm that module 635 can send a confirmation signal equally, attempt carrying out signal communicating by the second expansion bus interface 62 and control module 80.

As shown in Figure 3, when control module 80 provides the second expansion bus 82, confirmation signal is just sent to control module 80 by the second expansion bus 82.Control module 80 is after receiving the confirmation signal, and just can send a corresponding feedback signal, this feedback signal is also sent to expanding device 60 by the second expansion bus 82, and now, detection module 633 can detect that feedback signal produces.Once detect that feedback signal transmits from control module 80, execution module 634 just can make expanding device 60 link up with control module 80 executive signal by performing the second expansion bus interface 62.
Perform step 607: close the second expansion bus interface.
Otherwise, when the second expansion bus interface 62 is opened, if confirmation signal has not detected corresponding feedback signal after sending, namely represented control module 80 and second expansion bus 82 be not provided, therefore closed the second expansion bus interface 62.

Then step 702 is performed: whether detection control unit produces a feedback signal.
Similarly, after unlatching first expansion bus interface 61, whether detection module 633 can start to detect has feedback signal to transmit from control module 80.In the third embodiment of the present invention, its detection method can be same as the first embodiment, take time as foundation, that is detect within the schedule time and whether have feedback signal to produce, also the second embodiment can be same as, after sending confirmation signal, whether detection control unit 80 has corresponding feedback signal to produce, but detection of the present invention is not as limit.
Perform step 703: open the second expansion bus interface.
With first and second embodiment aforementioned unlike, in the third embodiment of the present invention, namely be convenient to there is the feedback signal detecting and transmit from control module 80 after the first expansion bus interface 61 is opened, expanding device 60 does not perform the first expansion bus interface 61 certainly, but first can close the first expansion bus interface 61, and open the second expansion bus interface 62, whether link up by the second expansion bus interface 62 and control module 80 executive signal to test expanding device 60.
