The TH7 motherboard features three USB ports and can be expanded to four via an expansion card. However, you'll find that only two of the motherboard's three ports work right out of the box. To enable the third USB port, you must set the motherboard's jumper caps, or "headers," on the board's USB pins. Before you venture out to enable your TH7's optional USB port, however, take some time to review the basics of the procedure.
Instructions
1. Power down your computer, then disconnect all attached cables. Place the tower unit on a level work surface, and remove your computer's case (see the Tips section).
2. Locate the "JP4" jumper set on your motherboard. You can find the jumper set above the board's 3V CMOS battery.
3. Place the first jumper cap over the first and third pins in the "JP4" jumper set. Place the second jumper cap over the second and fourth pins.
4. Replace your computer's case, replace it cables, then boot up your computer.
