All cellphone run on Lithium Ion batteries. These batteries, by nature(physics) have a max charged voltage of 3.4 to 4VDC. So, of your charger, or USB cable, has less than about 5 VDC, then either charger is defective, USB cable(if charging from PC USB port) is not a FULL USB(has data leads only wire, 5V power wire not carried through, PC does not supply 5V power to USB because it is turned off by a PC setting option, or a non-powering USB Hub or other device is in series with PC and Phone.

Are you sure you have identified the GND wire correctly? Measurements must all be made with one lead of your VoltMeter referenced to GND. Another consideration, some Windows Mobile phones will not charge off the USB cable unless the latest version of WM ActiveSync or Mobile Device software is loaded and running on the PC. These WM phones also will not charge from just any AC USB generic charger. Charger has to be for that particular phone, or phone manufacture, to be 'recognized' before provideing charge.

If you tell us what the monitor is doing, the solution may not require knowing what voltage is at what pin - especially since some of the voltages may be oscillating!

PRODUCT NAME
FRONTX USB Type A Internal

PRODUCT CODE
CPX101-2

BAY USAGE
Half of large bay

CONNECTORS
USB type A female
1x5 header connector female

CABLE
USB cable (UL 2725)
Length - 2.5 feet (762 mm)


WIRE ASSIGNMENTS



Red: + 5V / Voltage + / VCC
White: D - / Data - / USB -
Green: D + / Data + / USB +
Black: GND / Voltage - / Ground
Black: S-GND / Over Current / Shielding

The S-GND wire is fatter and can be easily recognized. The connection of S-GND wire to the header pin is optional.

HEADER CONNECTION GUIDES


Diagram 1: On most motherboards, the USB header/pin-out consists of 9 pins arranged in 2 rows, which allows for 2 USB connections (i.e. USB1 and USB2). Normally, the pins for USB1 and USB2 are in seperate rows.
Diagram 2: Simply plug the connector onto the 5-pins row, and make sure that the pin assignments and wire assignments are matched correctly.
Diagram 3: Alternatively, you can plug the connector onto the 4-pins row, and leave the S-GND wire unconnected.
You might have to rearrange the wires to match with the pin assignments, or change the header connector if necessary, depending on the layout of the USB header.
On some motherboards, there is a NC pin in the USB header. You can connect the S-GND wire onto this pin. NC simply means "no connection" and NC pin is an "empty" pin.
2X5 PINS HEADER
Refer to the diagram below, for 2x5 pins header, simply plug the connector onto one row of the pins, and always make sure that pin assignments and wire assignments are matched correctly. You might have to rearrange the wires if necessary.


2X4 PINS HEADER
Refer to the diagram below, for 2x4 pins header, simply plug the connector onto one row of the pins. Please note that there is no S-GND pin in this header. You can leave the S-GND wire unconnected. You might have to rearrange the wires if necessary, in such that the wire assignments and pins assignments are matched correctly.



ACTIVE PINS NOT IN THE SAME ROW

On some motherboards, the 4 active pins are not located in the same row, as shown in the example below:

To connect to this type of USB header, you need to change the header connector to 2x5. Simply rearrange the wires within the 2x5 connector to match with the pin assignments. If the green wire is connected to the USB2+ pin, the white wire must be connected to the USB2- pin. The red wire can be connected to any +5V pin, and the black (GND) wire to any GND pin. If there is no S-GND pin provided, you can leave the S-GND wire unconnected.




hope it helps

HOW TO CONNECT FRONT AUDIO PINS


the connector is marked F_audio and it is located directly behind the rear facing audio jacks. should be only one plug either marked "hd audio" OR "ac97 audio". some cases are setup for either, but you only need one of them depending on what your motherboard supports.

11) F_AUDIO (Front Audio Connector)
This connector supports either HD (High Definition) or AC97 front panel audio module. If you wish
to use the front audio function, connect the front panel audio module to this connector. Check the pin
assignments carefully while you connect the front panel audio module. Incorrect connection
between the module and connector will make the audio device unable to work or even damage it.
For optional front panel audio module, please contact your chassis manufacturer.
By default, the audio driver is configured to support HD Audio. To connect an AC97 front panel
audio module to this connector, please refer to the instructions on page 72 about the software
settings.

However, brand name manufacturers often build proprietary power supplies or make up their own color coding, so I wouldn't throw out a power supply that supplies 5V where you think it should supply 3.3V. It's more likely a proprietary design than a failure.
