Patent ID: 8234426

Claim:
A switching interface method for a multi-interface storage device, wherein the multi-interface storage device having different transmission interfaces, and a controller electronically connected to the transmission interfaces and having a predetermining list storing different priority weights for the transmission interfaces, standard protocols for the transmission interfaces, linking procedures for the transmission interfaces; and the switching interface method comprises steps of: (a) receiving an external linking request; (b) selecting one standard protocol corresponding to a highest priority weight of the predetermining list; (c) comparing whether a format of the external linking request complies with the selected standard protocol; wherein if the format of the external linking request is complied with the selected standard protocol, down-loading and executing a linking procedure corresponding to the selected standard protocol to enable one transmission interface corresponding to the highest priority weight; and if the format of the external linking request is not complied with the selected standard protocol, selecting another standard protocol in sequence from high to low priority weight until the format of the external linking request is complied with the selected standard protocol, and further executing a linking procedure corresponding to the selected standard protocol to enable one transmission interface corresponding to the present priority weight; (d) providing a selection of switching interface; and (e) determining whether another transmission interface is selected by the selection of switching interface; if so, disabling the present enable transmission interface and executing the linking procedure corresponding to the selected transmission interface; and if not, the present enable transmission interface is not disable.
