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,

    I would like to get wiring diagram so I can hook up usb

    The USB connectors are clearly marked on the motherboard.
    There should be an extra set of pins that are not used and you can plug in the USB connector there.
    The connector will have pins that look like this:
    ..... (1,2,3,4,5)
    .... (1,2,3,4)
    You don't use pin #5 on the top row.
    Pin #4 on each row is ground.
    VCC+ goes on pin #1 on each row.

    I have problems with usb my usb have 10 pin and sales usb multi funcion usb by 9 pin..

    Not a problem. The 'missing' pin is used as an orientation key. that pin end of the connector is the ground side (shield on cable). Opposite end is the 5 volt supply for the USB device.

    I have the same problem!!!

    Diagonally opposite to where you connect your mouse and keyboard, there will be pins for connecting front panel connectors. You can identify them by the names like SPK or Speaker written near them. You just have to match the front panel connectors with that of the pins. USB pins will be near these pins and will be labled as USB5 or USB4 on the motherboard. USB front panel connector can be inserted in only one direction.

    Front panel connectors/jacks is not working

    OK--usually what you will find from the front is 3 connectors.
    One will be a solid block that has one blank hole which is the key. That will plug into the corresponding pins on the motherboard--usually toward the back of the case.
    There will be another other wire that terminates in two plastic connectors. These are the USB connectors. Sometimes the connectors are in two parts. One is a 3-hole and one is a 1-hole. Usually you will find two sets as they sort of go together.
    The pin configuration on the motherboard looks like this ::::.
    The single pin on the end is not used. The other ones are connected with the plastic connector on the first three starting at the left, with the end marked VCC to the left. The fourth pin is the ground which is usually the separate connector.
    The second USB connectors are plugged in right next to the first--so each block of pins controls 2 USB ports.
    Hope this helps.
