    Sorry, but I do not see any solution. All I see is the words "here are the connector and their pin out" nothing else no links or others words of description or diagram.

  • mkiefer Jun 11, 2009

    These links must not be Mac compatible. I will have to find a windows PC to check them out.

  • mkiefer Jun 11, 2009

    I am using Firefox and on both the mac and windows computer. When I click on the links it says that this page can not be found and there is an error of a 404.

  • mkiefer Jun 11, 2009

    Ok, it is And for the pictures i can see your picture and many others on the page. You should be a white male with dark hair.

    I received the email with the jpegs. The usb ports work but I have no way at this time to test front audio, The case connection state it has something different than the way it states on jpeg. so I will have to leave at it is.

I believe you're referring to the AOpen MX46-533V

The Front Panel USB header is Blue in color, and located in-between the white No.3 PCI expansion slot, and bottom edge of the motherboard;

With the motherboard in the installed position;
5 pins across the Top row, 4 pins across the Bottom row.

Pins across the Top row are numbered EVEN
Pins across the Bottom row are numbered ODD

Starting on the Left side coming across to the Right, Top row;
Pins 2, 4, 6, 8, and 10

Starting on the Left side coming across to the Right,
Bottom row;
Pins 1, 3, 5, and 7

There are TWO USB connectors supported off of this USB front panel header.

For one of the USB front panel connectors;

A) Pin 1 is USB PWR 0
Goes to the VCC contact pin on the USB connector.

B) Pin 3 is USB_FP_P0-
Goes to the D- pin on the USB connector.
(Data - )

C) Pin 5 is USB_FP_P0+
Goes to the D+ pin on the USB connector
(Data +)

D) Pin 7 is Ground (GND)
Goes to the Ground (GND) pin on the USB connector

E) No pin 9

F) Pin 2 is USB PWR 0

For the other Front Panel USB connector;

A) Pin 2 is USB PWR 0
Goes to the VCC pin on the USB connector

B) Pin 4 is USB_FP_P1-
Goes to the D- pin on the USB connector

C) Pin 6 is USB FP P1+
Goes to the D+ pin on the USB connector

D) Pin 8 is GND

E) Pin 8 is USB_FP_OC0
Leave unconnected

This is more information on a standard USB connector pinout,

( A USB connector, and a USB plug are not wired the same.
The plug is wired backwards from what a connector is.
Otherwise you would have power and signal going to the wrong pins, and burn the USB Front Panel header out on the motherboard )

AOpen MX46-533V motherboard manual, but it is in Japanese.
May be one in English out there.
The Front Panel header pinout, USB header pinout, etc, is easily cross identified,

Aopen ax4bs no audio device found.

I've tried this and your right. It is the Jumper Caps missing causing your audio not to work. It should work. Maybe your diagram is up side down? Or maybe it is the wrong jumpers?
