Asus Motherboard Internal USB Header PinoutsWritten on April 8, 2010 by
When connecting front case USB ports directly to the motherboard, use the diagram below to identify the correct pins for each cable.
V is the voltage rail carrying +5VDC, and sometimes goes by VCC or +5. The wire that connects to it should be red.
- and + are the data transmission pins, and sometimes goes by D- and D+.
G is the ground pin. The 'shield' pin (to the right of the top ground) is not used. The wires that connect to the ground and shield pins should be black.
