Abstract:
1. A multi-functional electronic card with multiple input/output (I/O) interfaces, comprising: a multi-I/O interface unit having a plurality of interface ports arranged to be connected to a host, wherein, said multi-I/O interface unit is further arranged to automatically disconnect, and cause to be off-line, all said interface ports except one interface port when said one interface port is inserted into the host; at least one functional device, and a multi-interface and multi-functional controller connected to the multi-I/O unit and the at least one functional device and arranged to select at least one functional device, wherein signals of the multi-I/O interface are converted into signals of the selected at least one functional device so that the host can access the selected at least one functional device, wherein the multi-I/O interface includes at least a first interface port and a second interface port, a first detecting card signal loading device and a second detecting card signal loading device corresponding to the first interface part and second interface port, respectively, and a switch means, wherein the first and second detecting card signal loading device is arranged to detect whether a corresponding interface port is inserted to the host and, if the corresponding interface port is inserted into the host, to control the switch means to disconnect the other interface ports so that the other interface ports are off-line, and wherein the switch means includes first, second, third and fourth switch devices: the first interface port is connected to the first detecting card signal loading device and the first switch device; the first detecting card signal loading device is connected to the fourth switch device; the second interface port is connected to the second switch device and the third switch device; and the second detecting card signal loading device is connected to the second switch device.
