Wiring Diagram For Usb flashdrive


click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers


if you can see your usb drive but its not working

ports (com&lpt) right click update driver if this fails to fix the problem


check the USB leads that attach to the motherboard usually ((red white green black)) make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts


or
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

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.

How do i hook up usb button in intel 845 motherboard


Well, that's a start. You know you have an Intel motherboard in your eMachines, that uses an Intel 845 motherboard chipset.

It is an Intel D845GVSR motherboard.

http://www.intel.com/support/motherboards/desktop/d845gvsr/sb/cs-008823.htm

Left-click on the blue -
Intel Desktop Board D845GVSR Product Guide (PDF)

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
(I would advise upgrading to Adobe Reader X { 10 }, however, if you don't have it )

After you click on the above link, it may take up to 30 seconds before the first page comes up. (Took 6 seconds just now. Adobe Reader X, and medium speed DSL connection)

At the top of the PDF file, is the PDF file page number box.
It is to the left of the Down Arrow.
Go to Page 11.
T is the Front Panel USB header.

This is where the USB ports on the front of the computer, (Front Panel) connect to.

Go to Page 31.
E is the Front Panel USB header.
The Front Panel USB header is J9F2.

Observe the numbers next to the pins.
Go to Page 33.
This is the pinout for the Front Panel USB header, using those contact pin numbers.

1, 3, 5, 7, and 9 = one USB port
2, 4, 6, 8, and 10 = one USB port

Notice pins 9 and 10 are not used.

You can connect two USB ports to this header.

The pinout of ANY USB connector, female, or male, is set to a Standard.

This is the standard pinout for USB connectors,

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

In case you cannot download the Intel D845GVSR motherboard manual;

Looking at the motherboard in it's normal position, installed into the computer case, the USB header is on the Bottom edge of the motherboard.

It is to the immediate Right, of the bottom white PCI slot (PCI 3)
It is to the Left of the motherboard mounting hole.
It is Below the Intel 82801DB, Southbridge chip.

Two rows of pins.
5 across the Top row, 4 across the Bottom row.

STARTING on the Left side, (Towards the white PCI slot), and going towards the Right, the pins on Top are numbered,
Pins 2, 4, 6, 8, and 10

STARTING on the Left side, (Towards the white PCI slot), and going towards the Right, the pins on Bottom are numbered,
Pins 1, 3, 5, and 7

Pins 1, 3, 5, and 7 = One USB connection
Pins 2, 4, 6, and 8 = One USB connection

Pin 9, and Pin 10 are Not used. (N/C. No Connection)

A) Pin 1 is for Power

B) Pin 3 is for D-
The Data, or Signal wire. It is the Negative connection

C) Pin 5 is for D+
The other Data, or Signal wire. It is the Positive connection

D) Pin 7 is for Ground

Going to the other USB header;
A) Pin 2 is for Power

B) Pin 4 is for D-

C) Pin 6 is for D+

D) Pin 8 is for Ground

For additional questions please post in a Comment.

Out of curiosity which eMachines is this?

Sony walkman NWZ-S754 Recharge is through computer - but can I recharge it via mains or in car.


Yes you can charge your player through main. All you need is a converter which connects to the usb cable to the plug. They are available in the market so you will need to look for it. Or you may find it at any electronic store.
