  1. Hello,
    i just received my new motherboard, asus a8n, and i;m trying to connect my case's front usb panel with the motherboard.
    The motherboard's pins are labelled:
    - - - - - - - - - - - - -
    | +5v P6- P6+ GND NC |
    | +5v P5- P5+ GND |
    - - - - - - - - - - - - -

    As you can see, the first row has 5 pins, while the bottom one only 4.

    My case's front panel has 8 pins, labelled
    Power
    Power
    D2+
    D2-
    Gnd
    Gnd
    D3+
    D3-

    As you can understand, the pins of the panel are not grouped together.
    Where must each usb panel pin go on the motherboard?

    My guess is that the matches are:

    +5v ----> power
    +5v ----> power
    p5- ----> d2-
    p5+ ----> d2+
    p6- ----> d3-
    p6+ ----> d3+
    gnd ----> ground
    gnd ----> ground
    NC ----> unmatched

    note that the p5+-,p6+- pins on the two other usb ports on the motherboard, have other names.ie one has p7-,p7+,p8-,p8+ and the other has p9-,p9+,p10-,p10+

    Is my assumption correct? if yes, why is NC alone?
