Pleasure to see a fellow brown are we related ? :->

have you performed a test of each wire with a multi meter
to determine if each wire is indeed not broken ( open circuit )

if things check out ok with the multi meter , then it's time to start
digging deeper , such as asking yourself if you have indeed ENABLED the usb header at the bios level and has an IRQ that
does not conflict with other devices.

Also you'll want to make sure a driver is properly loaded for each
USB port , sometimes we forget to do all these things.

if all checks out after that , it's time to start getting suspicious
of the device being plugged in to the port , a dirty port can mean loss of connection , silly but so true.

if all checks out after that but still no luck , it's time to start asking yourself if you want to test things farther with extensive
checking of each USB port to make certan each port can read and write , this can be done with certan software.

if everything checks out at that point but still no luck ,
it's time to start asking yourself if you've made a boo boo
by loading an incorrect Operating system, ( rare )

I hope this information has been helpful , sometimes
we fail to get our trouble shooting ducks in a row.

Do you have any user manual for front panel usb

(MSI PM8M-V H, is version 2.0 )

Hover your mouse cursor on the Download tab.
(Overview / Specification / Download / Support / etc.)

In the drop down list, click on - Manual
Under the subheading - Download, click on the blue -
M7104v1.0.zip

[ This is a Zip file. A Zip file is a file that is compressed, to send easier. The above manual is for the M7104v1.0
It will work for the version 2.0 also.

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)

http://pinouts.ru/Slots/USB_pinout.shtml

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.
Why?

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.

For additional questions, or clarification to anything I have stated above, please post in a Comment.

I have an xblade case and have 2 usb ports in the front of this case. I have the motherboard 945G7MD 8EKRS2H and have 2 green squares that say USB 1 and USB 2 with 2 rows of pins top row has 4 pins and...


ok, here goes

pin 1 is vcc1 (red in my case)
pin 2 is data -1 (white)
pin 3 is data +2 (green)
pin 4 is ground (Black)

I would say that pin 1 will be farthest from the single 5th pin, on my machine I havent connected anything to the 5th pin and all is well

Hope this helps, I had to figure it out the hard way and didn't do any damage by wiring wrong once or twice.

You will need to get a usb expansion card. These can be found at Best Buy, Newegg.com, tigerdirect.com, pc-connection.com etc...

Some manufactures ship with newer motherboards a usb expansion slot using the motherboard jumper configuration but your motherboard must first be able to support this type of expansion.

I recommend the pci usb expansion. They plug into your PCI slot and give you 2-4 extra USB slots in the back of your computer.

ASUS P4SDX USB Ports not recognized as USB2 HS Ports


The message comes up when a USB 2 device is connected to a slower USB 1 or 1.1 port. It is only to advise you that the devise will operate faster on a USB 2 port. If your computer has only USB 1 or 1.1 ports, you will always see the message. You can buy and install a card with USB 2 ports and install it. It will come with the USB 2 drivers. Install the card and the drivers and then connect your USB 2 device to the new hardware and you should not see the message anymore.

Good luck, And let me know ho it works out for you.
