Matsonic MS9337c USB front Painel connector

I've got a computer case that has the 4 individual pins for the front connecting usb port. Does anyone have the pattern on the motherboard? I've tried the standard pin out and it didnt do anything tried the Gigabite standard and it didnt do anything. tried the pin out for another Matsonic mother baord and it KILLED 3 different usb devices. i guess it has the power in the wrong spot. i thought i just grabed a hand full of dead keyboards at first b/c it would detect them but wouldnt use them. the last one i tred on a different computer before i connected it. KILLED IT DEAD. PLEASE help. does ANYONE have a manual for this mother board?

    That link leads to a site that is trying to sell the domain. It had no mother board diagrams on it. I've also tried variations of it thinking you may have miss typed it. Thanks for trying, I've been searching a LOT with no luck..

Nope. We're just going to have to 'Wing it'

Long read, better put the coffee pot on.
(Oh and sum snacks! I like Little Debbies, Lol! All that good(?) whipped fat, and sugar)

The motherboard is shown as installed in the computer case.
I will use this orientation to explain the various cable, (Wires) hookups

We will be referring to the motherboard photo, and if you will scroll down, the motherboard layout as shown in an illustration.

Let's go to the illustration, and refer back to the photo.
Perhaps make it easy on yourself. Open the above link in two windows. One window with the photo, one window with the illustration.

1) The white 3-pin connector at the top of the motherboard, and to the left of the Ram Memory slots, is for the Processor Fan. It is labeled CPU_FAN1.

(CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short)

2) The Berg connector to the right of the Ram Memory slots, (Top right corner) is labeled JLPC1, and is ONLY used by the manufacturer for board level debugging purposes.
(Junction Low Pin Count 1)

3) The processor socket is labeled Socket AM2.
To the bottom Left corner is a 4-socket hole connector, and whitish in color, JPW1.
A 4-pin ATX +12 Volt power cable plugs in here.
General example of power cable, and respective connector,

Note the Lock on the side of the power cable's connector, and matching Tab on the motherboard connector. The Lock operates like a see-saw on a playground. Squeeze the top in to release.

4) Below JPW1 is SYS_FAN1.
This is where a computer case fan hooks up.

5) Look below the Ram Memory slots. There you will see 5 connectors labeled SATA1 through SATA5.
SATA1 is for the Harddrive. SATA2 through SATA5 are for optical drives, and additional SATA harddrives.

Bottom of motherboard come across from the Left side;

6) The front of your computer is the Front Panel.
JAUD1 is for the audio ports in the Front Panel

7) JAUX1 goes to the PRIMARY optical drive, if there are two optical drives. (CD/DVD drive)

8) J1394_1 is for the Firewire ports on the Front Panel. They will be labeled 1394, or similar. (1394a)

9) JSPD1: To my knowledge not connected.

From Frankenputer;

"Newer ATI cards that have HDMI have a built in sound processor. nVidia cards do not and will have a connection on them to input the SP/DIF connector(either by a cable connecting inside via the card to an outside SP/DIF connector, or a cable connecting an SP/DIF header on a mobo to the video card. This is so that both the HD video and Sound are transmitted via the HDMI."

10) JUSB1 has provisions (Contact pins) for hooking up TWO USB ports on the Front Panel.
So does JUSB2

JUSB4 through JUSB6 are for a USB port. One USB port for each one of them.

11) JFP1 is Junction Front Panel 1.
Another term used is the Front Panel header.

This is where the Power On switch, Power On LED light, HarDDrive activity LED light, and Reset switch, (IF used), hook up to from the Front Panel.

Note the two rows.
4 pins across the Top row
5 pins across the Bottom row.

The pins are numbered.
The pins across the Top row are numbered EVEN
The pins across the Bottom row are numbered ODD.

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

Starting on the Left side coming across to the Right; Bottom row,
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.
If not No Connection.

C) Pin 9 is N/C. Not Connected.
This is reserved for the factory to use.

D) Pins 2 and 4 are for the Power On LED (Light)
Pin 2 is for the Positive ( + )
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch

F) There is No Pin 10. This is called the 'Key'
Helps you orient the Front Panel cable's connector, to the Front Panel header.

USB cables for HP's are usually Black. Called cables because they have individual wires in them.

Each cable going to a set of two USB ports, in the Front Panel, for the USB1 and USB2 headers on the motherboard.

A card reader will use a USB header on the motherboard, or two of them.
The power cable to it is the same as used on a Floppy Drive,

This power cable goes to a SATA harddrive, or a SATA optical drive,

This is an example of a SATA data cable, and it's respective connector on the motherboard.
NOTE* Does NOT matter about color. Color of the connectors, or the cable.
Also look at the L-shaped opening, and the L-shape on the motherboard connector.

Plus a 90 degree elbow on the SATA data cable, is usually connected to a Harddrive, or Optical Drive.
A straight connector usually goes to the motherboard.

Often there is a 'bump', you press on top of the SATA data cable connector, to release it. The bump is a Lock.

Again color does not matter. The only time it may come close, is individual coloring of the SATA connectors on the motherboard, to distinguish their numbering.

(SATA1 Dark Blue. SATA2 White. SATA3 Light Blue.
SATA4 Yellow. SATA5 Red. SATA6 Black)

If the optical drive/s are IDE (PATA), they will use a standard 4-pin Peripheral power cable,

There are two USB headers on the motherboard for the Front Panel,
JUSB1 and JUSB2. (Junction USB 1 and Junction USB 2)

Looking along the bottom of the motherboard, FROM the Right going towards the Left;

JFP1 header; (Front Panel main wires)
Header with 4 pins on the Top row, and 5 pins on the Bottom row.

JFP2 header; (Dual color Power On LED, and Speaker)
Header with 4 pins on the Top row, {Speaker}, and 3 pins on the Bottom row.

JUSB2 header.

JUSB1 header.

EACH USB header will support TWO USB ports in the Front Panel.
JUSB1 supports two,
JUSB2 supports two.

For each USB header there are 5 pins across the Top, 4 pins across the Bottom.
The pins are numbered EVEN across the Top, and ODD across the Bottom.

Starting from the LEFT side going across to the RIGHT side;
on the TOP row for JUSB2 and JUSB1;
Pins 2, 4, 6, 8 and 10.

Starting from the LEFT side going across to the RIGHT side;
on the BOTTOM row for JUSB1 and JUSB2;
Pins 1, 3, 5, and 7. There is NO pin 9.

A) Pin 2 is VCC
B) Pin 4 is USB1-
C) Pin 6 is USB1+
D) Pin 8 is Ground

E) Pin 10 is USBOC

Pin 10 is N/C -> Not Connected.
It is there, and Pin 9 is not there, to key which way a connector can go on. Only ONE way.

F) Pin 1 is VCC
G) Pin 3 is USB0-
H) Pin 5 is USB0+
I) Pin 7 is Ground

There is NO pin 9.

(The USB technology used is USB 2.0)

Let's read together,
Under - USB pinout signals;

"USB is a serial bus. It uses 4 shielded wires: two for power (+5v & GND) and two for differential data signals (labeled as D+ and D- in pinout). NRZI (Non Return to Zero Invert) encoding scheme used to send data with a sync field to synchronise the host, and receiver clocks. In USB data cable Data+ and Data- signals are transmitted on a twisted pair. No termination needed. Half-duplex differential signaling helps to combat the effects of electromagnetic noise on longer lines. Contrary to popular belief, D+ and D- operate together; they are not separate simplex connections."

See the USB examples in the link above, where it labels the contact pins?
The MALE connectors are shown on the Left side.
The FEMALE connectors are shown on the Right side.

Your USB ports will be FEMALE, on the Front Panel.
They are also the A style. USB A style. The Top example to the Right.

Just noting the following in case for some reason, the wires coming from those contact pins in the female USB connector, are not color coded correctly;

Even after you have the wires sorted out, as to which contact pins they go to, DOUBLE-check again. Do NOT just go by the color code of the wires.

You do NOT want to accidentally connect the +5 Volts (VCC), to the Ground!

Explaining further;
You connect the VCC wire, (Red), of the USB port in the Front Panel, to the Ground pin on the USB header on the motherboard.

(Which means the Ground wire of the USB port, (Black), will probably also be connected to the VCC pin, on the USB header of the motherboard)

Zzzzzzap! There goes your front USB ports. Both USB front panel headers on the motherboard, will be DONE!

Make sure!

Going on;
1) VCC or Vcc, goes back relating to Transistor technology.
Just think of it as the Positive, or power wire.
It is.
It is 5 Volts DC.

2) GND is Ground. It's a DC circuit, and you have a Positive, and a Negative, or Ground.

3) USB1-
That is -> Data-

USB0 is for one USB port in the Front Panel.
USB1 is for another USB port in the Front Panel.

[ Each USB header on the motherboard can be connected, to TWO USB ports on the Front Panel.
Therefore for the two JUSB1 and JUSB2, you can connect Four USB ports in the Front Panel ]

Data- on one USB port in the Front Panel, goes to USB0-

Data- on the other USB port in the Front Panel, goes to USB1-

4) Data+
Same thing.
Data+ on one of the USB ports in the Front Panel, goes to USB0+
Data+ on the other USB port in the Front Panel, goes to USB1+

EACH side of JUSB1 and JUSB2, will support one USB port on the Front Panel.
Two sides per JUSB1 and JUSB2 = 4 USB ports on the Front Panel.

Location firewire input port

There isn't one on the back panel. You must connect the USB/1394 bracket that's included with the board to an empty slot on the rear of the computer and hook up its connectors INSIDE the computer to the appropriate headers on the motherboard: the purple firewire connector would connect to the purple header (DUH!) on the RIGHT in the pic below, it's a DOUBLE firewire header and it's the only place this bracket will fit. The yellow USB connector would go to any open USB header on the board (guess what color...) Very simple, really.

1f72ff6.jpg ed2998b.jpg

Optionally if your computer case has a built-in firewire port on the FRONT panel, as most do nowadays, you can connect that to the appropriate header on the board using the already-installed cable that's connected to that front firewire port (connect this one to the purple header on the LEFT, it's just a SINGLE firewire port.)
However, this header's pins will NOT match up properly with almost all case's front-panel firewire connectors. You would most likely have to switch around 2 or 3 of the little wires that go into the connector so that it matches the motherboard's pin-out.

It's clearly labled in the manual for the board, and isn't really all that difficult to switch the wires around, but I would recommend just going with the first option and connect the included bracket to the back since it was designed to go with this board and requires no modification.

Havimg prob with the 2 usb ports located in front

Hi manky, Normally front USB ports have a pair of 4 wire cable with connectors marked red wire is vcc; white wire is -D; green wire is +D; and black wire is gnd. The motherboard would normally have two pairs of dual pin connectors that would be sitting side by side or in-line with uneven pins - 4 and 5 pins; then another 4 and 5 pins. Please refer to the attached simple diagram for your connection. For some reason I couldn't get hold of a manual from the Gigabyte site of your particular model GA-81KHXT. Nonetheless hopes this works for you. Pls post again how things turn up. Good luck and kind regards.
