I have just recived a new product and I want to replace the permanent USB cable that is soldered to the board with a shorter female end USB. The problem is that when I disassembled the item I saw that the cable is soldered to 5 points to the board using 5 cables that come out of it. Now as far as I know USB 2.0 Type A has only 4 pins (Voltage, Data-, Data+ & GND).
How can I then connect it (The 4 pin female end USB) and why does it have 5 pins when on the other end were it connects to the computer it is a type A connector.

Since the product came with standard USB type A plug, the fifth wire would be connected to the metal chassis frame shield of the connector.
