1. A signal converter for an all-in-one USB connector comprising:

  • the all-in-one USB connector including a first port and a second port;

    a USB 3.0 signal interface and eSATA signal interface respectively connected to the first port and the second port; and

    wherein the USB 3.0 signal interface and eSATA signal interface are also configurable to be respectively connected to the second port and the first port;

    an inner communication interface connected to a data bus of a printed circuit board (PCB); and

    a processing unit connected between the USB 3.0 and eSATA signal interfaces and the inner communication interface and having an identifying and converting procedure, wherein the identifying and converting procedure has a first sub-procedure and a second sub-procedure, and wherein the processing unit periodically executes the first and second sub-procedures after the processing unit is actuated to detect the USB 3.0 and eSATA signal interfaces in sequence and determine whether a response signal is sent back from one of the USB 3.0 and eSATA signal interfaces.when a determined result is positive, the processing unit bi-directionally converts two different standard signals of the inner communication interface and one of the USB 3.0 and eSATA signal interfaces that transmitted the response signal.
