  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

    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 one has p7-,p7+,p8-,p8+ and the other has p9-,p9+,p10-,p10+

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