Small single post connetors and USB connector

System Board: A Open MX46-533V. Client asked me to repair computer's Front Panel USB connectors and sound. Running Win XP HE with a P-4 processor running at 2.79 Mhz. System has 2 GB PC-2700 RAM.

There are numerous little single post connecting wires hanging loose inside the cabinet! They are labeled but, while the System Board provides a number little pins for them to go on, I have no clue as to what goes where. The location of a schematic would be of great benefit. Thanks,

Cyber Mech

Front 4 usb ports and microphone and headphone jacks don't work but the rear usb and speaker jacks do work. I've had the computer new since 2009 and they have never worked.


it sounds to me like the wires from the front panel connectors are not connected to the motherboard inside the computer case, open the case up find the front connectors wires inside and find out if there are any connectors on the motherboard to plug them into.
the reason the rear ones work is because they are soldered directly to the motherboard.
good luck.

Plugigng of wire in board


Hello there,


Below is an image of *********** Board with number indication and wiring explanation. From your manual page 1-6 you can see the image below and 1-7 for the connector, jumpers, slots. as indicated in your problem I will only answer problems related to the wirings.


pcsyke_115.jpg

  • For the Front Panel


pcsyke_117.jpg
1. There are 8 wires from the front panel's casing, excluding USB connectors and front audio cable.

2. Just plug the front panel switch headers to the F_Panel main board connectors. 1 & 2 are positive, if the led do not light change polarity but Im sure it will.

Note:The mainboard provides a front panel connector for electrical connection to the front panel switches and LEDs. JFP1 is compliant with Intel® Front Panel I/O Connectivity Design Guide.


  • For the USB connectors


pcsyke_118.jpg

1. If your casing has a USB header on the front bezel you can put it on any connector. You can also purchase a USB module cable or an internal card reader and plug the headers to any of those connectors.


Note: Observe Polarity, do this Vcc, -Data, +Data, Gnd ,(NC) ground is always near to NC.

Plug it at your own risk, reference image are already shown.


  • Front Panel Audio connectors


pcsyke_119.jpg
1. Look for FP_Audio header from your casing and plug it to the connector.

*Asus recommend you connect a high definition front panel audio module to this connector to avail of the motherboard's high-definition audio capability.



Hopefully this information helps.


Thank you for using FixYa.

I want to connect My front USB to the Gigabyte MB ga-945p-s3 i dont know how to do it right if there is a video to show me how to do it, that would be great your help is needed thanks


There are two connectors on the motherboard marked F_USB1 and F_USB2 for the front panel USB ports. This is the page from the manual (you can download a copy here) for your board:

pgh_pa_guy_7.jpg
The pinout of each USB connector is the same, so it does not matter which one you use. Each connector supports two USB ports. The pin assignments are a standard, and the cable from the front panel USB connectors in your computer case may already have a plug on the end which will fit. Note the missing pin (pin 9); the plug is keyed so it will only fit one way so you can't put it on backwards.

If the front USB cable in your computer case doesn't have a 10-pin plug on the end, it will have a separate single-pin connector on each wire, and they will be marked with their function. Make sure you match each wire to the correct pin on the board, following the chart shown above.

You should have your front USB working very quickly. Thanks for using Fixya!

Where would I look for the usb port


Most Compaqs (in general all brands) have USB ports on both the front and rear of the case. The rear connectors are found where all the other I/O connections are located. They are flat rectangular sockets. When you want to plug in a USB device, you can plug into any open USB port. The plug will also only fit one way, so if it will not go into the connector just flip it over.

Front panel USB connectors are often hidden behind a door. Look for a swing-open or slide-down panel. On some cases the connectors may be on the top or sides.

When connecting devices such as a printer or external hard drive, you should use the rear-panel USB ports. These go directly into the system board and have the best performance. Front-panel USB connectors plug into the main board with cables. For most devices (including your SanDisk) it doesn't matter which you use, but the rear-panel ones are best for high-speed devices or moving lots of data.

You can usually find the user's guide online at the computer manufacturer's website, and that will show you where all the connector are on your system.

If this solution has been what you need, please take a moment to rate it. Thanks for asking here!

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.

Front usb connections


I finally found a solution, on a dead page in google cache only:
http://www.pcclub.com/forum/messageview.cfm?catid=27%26threadid=16567
The solution was posted by JontyBonkers.


The pins go like this:
1 2 3 4 5
_ 6 7 _ 8

1 = ground
2 = ground
3 = D1-
4 = ground
5 = D1+
6 = D2-
7 = D2+
8 = +5V

It seems that the case for those Packard-Bells had a small circuit board that divided the 5V line to both sockets.

D- are usually white, D+ - green, 5V - red, ground - black
