An interface connection method applied to a connection device. The connection device is configured to connect a host end having a first connection interface and a device end having a second connection interface. The interface connection method includes determining a voltage level of a detection pin; performing a first initialization when the detection pin is at a low level; providing an electrical power for detecting whether the electrical power is consumed or not when the detection pin is at a high level; sending a link signal when the electrical power is consumed; and performing a second initialization when the device end is detected to be in a ready state.
