Some Motherboards have a USB front panel header that allows an additional 2 USB ports. The ports can be connected either to the front or rear of the chassis by attaching a front panel USB cable. The header may be labeled “Front Panel USB” or “FNT USB” on the desktop board. The other way to tell where your usb goes is by the pins. Number 9 is missing. Number 10 is missing on the power and hdd connectors and number 8 is missing on audio. It may vary, however this is the most common.
Note: Improperly connecting the USB cable may cause the external ports to not function properly, damage to the desktop board or damage to the external device. Proper connection is recommended. Please research your motherboard as there are so many different combinations out there now.
Below is a diagram of the most common layout of a front usb connector.
