    Unfortunately this manual does not give this info

  • mike1941 Nov 19, 2008

    Dowload centre for Abit KT7A does not give details of USB pins

  • mike1941 Nov 19, 2008

    Sorry this does not help either

  • mike1941 Nov 19, 2008

    Not on this one it doesn't!

  • mike1941 Nov 19, 2008

    Yes i've seen this but no pin numbers are shown in detail like for the other connectors

  • mike1941 Nov 19, 2008

    What i need is the pins numbered 1 to 9 and the assignment of the leads marked G, Port+, Port-, and VCC

  • mike1941 Nov 19, 2008

    An extremely comprehensive site thankyou but still does not answer my problem!

  • mike1941 Nov 23, 2008

    Have now solved the problem with patience and a systematic series of elimination. But thanks to all.

Here is the pinout, with pin numbers, this is what you are asking, if not , you need to explain why, since here you have USB pinout:

Abit KT7A motherboard need the - 3472e2f.jpg

Pin one is at the lower right hand corner.

If this is not what you are looking for you need to explain Why.

This is USB pinot for usb connector on your motherboard.

Let me know .

Thanks.

    I do not know if you can see all solutions , this had ben posted many times.

    Evidently the system on Fixya is disfunctional.

    Here
    is the pinout, with pin numbers, this is what you are asking, if not ,
    you need to explain why, since here you have USB pinout:



    Pin one is at the lower right hand corner.
    Pin 2 is in front of it.
    then pin three bove pin one.
    pin 4 above pin 2 and so on.



    If this is not what you are looking for you need to explain Why.

    This is USB pinot for usb connector on your motherboard.

    Let me know .

Hi,

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.
Abit KT7A motherboard need the - d49249e.jpg
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Wiring scematic for a gateway gt5636e


Gateway Support > GT5636e Desktop PC > Main Support page,

http://support.gateway.com/us/en/s/PC/R/1014825R/1014825Rnv.shtml

Click on Components in the list.

Scroll down.
Under the black - Motherboards - subheading click on the blue -
4006245R - Intel (Stoughton) G965 motherboard with LPT port

In the list click on the blue - Product Views

B - Processor Core Power Connector
That is to the LEFT of the processor socket.

This is a general example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Note the LOCK clip on the power cable's connector, and the matching TAB, on the motherboard connector.
When the power cable is deemed to be plugged in Tightly, and Correctly; the Lock clip will be hooked over the Tab.

The 24-pin ATX main power cable's connector, and matching motherboard connector; has this feature also.

D - CPU Fan Connector
Go straight up, from the processor socket to the edge of the motherboard, then to the Right.

Notice how the motherboard connector is Keyed, and the matching plug connector that goes to it.
Same thing for all those white 3-pin connectors, on the motherboard.

[CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Does NOT mean Personal Computer ]

G - Floppy Disk Drive Connector
Black 34-pin connector for a Floppy Drive.
It is next to the White 24-pin ATX main power cable connector.
Right side of motherboard, towards the Top.

If I were a betting man, I would bet you aren't using it. No Floppy Disk Drive.
But I'll tell you what.........it's nice to have.
A Floppy Disk Drive doesn't take squat to run.

Need to flash the BIOS after the BIOS has been corrupted, you can use a Floppy Disk/s with the BIOS upgrade info on it.
Jus sayin'.

H - ATX Power Connector = 24-pin ATX main power cable connector.
This is a general example of a 24-pin ATX power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

NOTE* Color of connector does NOT matter ]

Location covered above. Right upper side of motherboard

I - Rear Chassis Fan Connector

With the huge(?) image of the motherboard on Gateway Support, and the equally sized images available on the internet; you're on your own.

Easy to find though. Small white 3-pin connector, with Rear Fan printed next to it. I'm betting to the Left, of the aluminum finned Heatsink, for the Northbridge chip. (Below processor socket)

Next to an Electrolytic Capacitor, that has a gold, and black plastic sleeve.
Used for a computer case fan in the Rear. Draws air OUT of the computer case. (Out the back)

J - PCI Express x16 Connector.
THIS, is where the graphics card goes.
A PCI Express graphics card.

OR, you can use a PCI graphics card, in one of the white PCI slots.
I would NOT. The PCI technology is NO where near, the PCI Express technology,

http://en.wikipedia.org/wiki/Pci_express


The front of your computer is the Front Panel.
L - Front Panel Audio Connector, is for the audio ports in the Front Panel.
FP_AUDIO

It is to the Left of the white PCI slots, and the header itself is Yellow in color.
Do not know the individual pinout of this Front Panel Audio header.

You have a plug connector that plugs onto it.
You can see the header is missing one pin. The missing pin is called the Key.
This shows you how to line up the plug connector to it.

If you need the individual pinout, trace the individual wires to the Front Panel audio ports.

N - HD Audio Link Connector
Plug connector goes on it also.
Location believed to be Bottom edge of motherboard, towards the Left.

O - Parallel ATA IDE Connector
Just the usual 40-pin IDE (PATA) connector.
(Actually, ONLY 39 pins )
Bottom edge of motherboard, black in color

ALL three harddrive options are SATA, so you won't be using it for your harddrive.
The optical drive you have is IDE (PATA), so this connector is where it plugs in.

Notice the cutout in the side of the connector. This is a Locating Notch.
Lines up with a Locating Lug, on the flat IDE ribbon cable, for the optical drive,



P - IEEE 1394 Connector
It's for the Firewire (1394a) ports in the Front Panel.
Plug connector goes to it.
Color is Blue, and it is in-between the white PCI slots

Q - USB 2.0 Connectors
Two of them side by side, but separated by a small Electrolytic Capacitor.
Black color for these USB headers.

They are for the Front Panel.
Location to the right of the black IEEE 1394 connector, bottom edge of motherboard.
They utilize the USB 2.0 technology.

ONLY one is marked. -> USB 2.
It has FP_USB_2, printed under it.
Front Panel USB 2.
The other one to the Left, is FP_USB_1.

EACH of those headers supports TWO USB ports.

A (Media) Card Reader has TWO cables, and uses ONE USB header.

One of those USB headers then, can be used for a Card Reader in the Front Panel.
The other USB header for Two USB ports in the Front Panel.

R - SATA Connectors
You see there are SIX.
Marking starts with SATA 0. (SATA0)

SATA 0 is for the SATA harddrive.
SATA 1 is for an optical drive (CD/DVD drive)

IF, you are using TWO optical drives, the MAIN optical drive connects to SATA1. The secondary optical drive connects to SATA2.

Make sure if you are adding a SATA optical drive, (That the computer did NOT come with), that you go into BIOS Setup; and ENABLE that SATA connector you wish to use.

HOWEVER,............the beauty of SATA is, that you can plug ANY device into ANY SATA connector; and BIOS will find the device.

Want to plug an optical drive into SATA0? No problem.
Want to plug the SATA harddrive into SATA 5?
No problem.

Just make SURE that SATA 5 is ENABLED, in BIOS Setup.

S - Front Panel Connector

Again, the front of your computer is the Front Panel.
Moving on.......
The area of contact pins on the motherboard, that the Main wires from the Front Panel connect to, is the Front Panel header.

Here you can see the individual pins, are marked by colors on the header itself.
Pin 2 is next to the Green pin, on the Bottom row to the Right.

Pin 1 is above it.
Looks confusing, because Pin 6 for the header above it, is marked right there also.

Pin 8 is marked on the bottom of the header.
Pin 9 is marked on the Top of the header, all the way to the left; except some 'crackhead' marked it upside down. (lol)

So,........pinout..........

Starting on the Top row, at the Right side; going towards the Left,
Pins 1, 3, 5, 7, and 9.

Starting on the Bottom row, at the Right side; going towards the Left.
Pins 2, 4, 6, and 8. There is NO Pin 10.

1) Pins 1 and 3 are for the HarDDrive activity LED.
(Light Emitting Diode, so I'm not going to refer to it as a light.
It is. LED states that)

Pin 1 is for the Positive ( + ) connection.
If the HDD LED is dim when the harddrive is active, switch the wires around.

2) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

3) Pin 9 is 5 Volts.
5 Volt power. That is why it is marked as +5 Volts.
Used for the factory to test with.
It is N/C. Not Connected.

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

5) Pins 6 and 8 are for the Power On switch.

6) Again, there is NO Pin 10.

T - Auxillary Front Panel Power On LED Connector
Right above the Front Panel header.

Freaking beats me why it would even be on there.
To iterate;

There are only 2 pins. This type of Power On LED header has 3-pins usually.
It is used for a dual color Power On LED.

Used back in the day when computers had the 'Turbo Mode' feature, and 'Normal Mode' feature.
Dual colors of dual color Power On LED was usually Green, and Yellow.
Green for Turbo Mode, Yellow for Normal Mode.

Was in reality a bunch of cr@p.
Turbo Mode was the computer actually operating in NORMAL mode, while Normal Mode was the computer was operating slower.
Just another gimmick.

{'Buy me! I'm a shinier Red bike! }

Probably why Gateway states it does Not support this feature.

U - Clear CMOS Jumper
If you do not know what this is for, LEAVE IT ALONE.
(He states politely)

V - Front Fan Connector
Yes, you guessed it. For the computer case fan in the Front, that draws air INTO the computer.
Location? Close to the round CMOS watch type battery.

X - Intrusion Switch Connector

Can't believe they are still using this cr@p.
It's so if someone opens the computer case, the power to the motherboard is turned off.

Good feature, but if the person working on the computer; doesn't know enough to unplug the computer from power FIRST, then chances are they do Not know about Anti-Static Procedures either.

Don't FOLLOW Anti-Static Procedures, you can use the motherboard for a Frisbee, or expensive paperweight.

Static shock the motherboard, is why.
Goodbye Processor (CPU), Ram Memory, motherboard, graphics card, (IF used)......and who knows what else.

DO NOT connect anything to it. Leave alone.

(If you do though, it has to be ENABLED in BIOS Setup; to use this feature)

For additional questions 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-

How do I connect the front usb wires to my fic c51g motherboard header?


How to Install Front USB by Connecting Front USB Ports to a Motherboard?In order to have front mounted USB you must have 3 things.
  1. A case with USB ports in the front of it.
  2. A motherboard that supports front USB (usually)
  3. Appropriate wiring between the USB port and the motherboard
A case can support front USB in two ways: via a pass thru connection, or via a port to header connection. The former, pass thru connection, is compatible with all motherboards that have USB ports. Pass thru front USB Pass thru front USB works by having the ports on the front of the case connect to either a standard USB cable, or a fairly small rounded cable. The cable goes from the front of the case to a special slot cover with either a hole (for the standard USB cable) or a special connector for the rounded cable. If the pass thru USB had a standard cable, then you would simply plug the standard cable into one of your back USB ports. If it had a rounded cable, then you have a secondary attachment with something that looks like an old style SCSI connector. The attachment plugs into both the slot cover, and the back USB ports. The draw back of pass thru front USB is that you lose the ports in the back.

Many 3rd party devices that add front USB to a system use the pass thru system. A good example is this now discontinued Front IO panel

Front USB via a Port to Header connection In order to hook up a Port to Header connection you have to make sure that the wires from your port will connect to your motherboard's header. To do this you need to know what header you have, and what type of connector you have on the wires. You'll find information on both below.

Almost all motherboards these days have a USB header. Due to size and cost restraints many motherboards only have 2 USB ports on their back panel, but often they can actually support more then 2 USB ports. They will typically support additional ports via the use of a USB header. A USB header is either a single or double row of header pins on the motherboard that can be used to add additional USB ports to a computer via the use of an appropriate set of header connectors, wires, and a USB port. Each pin on the header corresponds to a wire inside a USB cable. These pins must be clearly marked so that you can hook them up to the wiring correctly. There are 2 common layouts for a USB header.

Intel Standard USB header Layout: (used by over 90% of motherboards)

instusb1a.jpg

Gigabyte Style USB header Layout: (used most commonly on Gigabyte brand motherboards)

instusb2b

Now that we know the types of headers we have to take a moment to understand the USB wiring. Understanding the wires First off: All USB cables have 5 wires. 4 of these wires are actively used. Here's a reference from the official USB standard.

instusb3

On a front mounted USB port you'll have either the first 4 wires connected to properly colored wires (red for power, white/orange d-, green/yellow d+, black for ground) or all five wires attached to the port (same as the former, but one extra black wire). Now where it gets tricky is how to attach each of those wires to corresponding pins on the motherboard.

The wires are "tailed" (attached to a header connector) using any one of a number of different types of connectors. Below you'll find a list of the common ones.

Common USB case header connectors 4 joined pins + 1 extra ground.
usbheader

Compatibility: Compatible with both header arrangements because of the extra ground. May not work with some odd arrangements To hook up carefully match each pin. For the Intel hookup you'll have the extra ground wire not attached to anything. For the Gigabyte hookup you'll have the extra ground hooked to ground pin on the motherboard, and the standard ground jumper will be over the missing pin on the header.

All pins separated

instusb6

Compatibility: Compatible with every header. If all the pins are separated the only real issue is lining up the pins with the appropriate places on your header. It should be compatible with all headers. Just make sure you read the writing on each individual connector. Please check the troubleshooting info at the end of the article for important information on this configuration

Power and Ground separate, d-, d+ joined Lian-Li style

Compatibility: Compatible with all common headers. This sort of arrangement is common to almost all Lian-Li cases. Make sure that you get the wires connected to your header in the proper order. If you find that the port does not function the most common cause is accidental reverse of the d-,d+. Try switching it.

All pins joined Intel style easy connector

making the Connection Once you know what type of header you have, and what type of connector you have on the wiring, you need to connect the two of them. In order to do this, you must first figure out what pin goes with what part of the connector. To do this, you should first consult your motherboard manual. Below you'll find an excerpt from a fairly recent motherboard manual for the Asus A7M266 motherboard. It's typical of a motherboard manual for a board using the Intel standard USB header.

instusb5

The first thing you'll probably notice is that the wiring from your case and the names of the pins might not quite match up name wise. This is a common problem. Motherboard makers and case makers really haven't decided on what to call each pin. Here's a rough list of names.

Power may be called: P, VCC, USB Power, Power, and PUSB. On wiring it's always red. Ground may be called: G, GND, Ground, and GUSB. D- may be called: USB-, USBP-, D-, or just -. D+ may be called: USB+, USBP+, D+, or just +.

To complicate things a bit more you'll probably notice that there's a number before each one. Take a look at the picture above from the USB hookup diagram for the A7M266.

You'll see that Asus decided to number the middle pins. On the first row (starting with pin 1, and marked with a 1) you'll find that they list D- as USBP2-, and D+ as USBP2+. The number 2 tells you a few things. First off: It's the 3rd USB port on the motherboard (they started numbering at 0), second it tells you that that D- and D+ must be used for the same port. Case manufacturers are just as likely to number their ports differently.

Take a look once again at the 4-pin joined picture: usbheader

Notice that you're D-'s have either a 1 or a 2 on them. These also tell you that they are part of the same USB port. (Remember, 1 port has 4 required wires). The numbering on the connector and the numbering on the header doesn't have to match.

To connect everything grab the following connectors: a same number D pair, (D-, D+), 1 power, and one ground. If your power and ground are numbered make sure all 4 are the same number.

Tip: Most cases that use all separated pins will bundle these together for you to make it easier.

Now, take your Power, D-, D+, and Ground and line the connector up with the appropriate 4 header pins on your motherboard. The header pins will be in a row under the Intel style, and in the Gigabyte style it will either be a row of 1 pin, a gap, and then 3 pins, or 3 pins, a gap, and then 1 pin. Press the connector down over the header pin and make sure it's firmly attached. Once you have done this go back and grab another set of connector wires (Power, D-, D+, Ground), and hook up your second front USB port. If your case has more then 2 front USB ports, and your motherboard has more then one front USB headers, then repeat the above as necessary.

Example: If you were hooking up the front USB on a A7M266, on a case with the pictured 4-pin joined connector type then: VCC lines up with USB Power, USBP2- lines up with USB1-, USBP2+ lines up with USB1+, and GND lines up with GND. For port 2, VCC lines up with USB Power, USBP3- lines up with USB2-, USBP3+ lines up with USB2+, and GND lines up with GND.

3.5'' internal memory card reader/writer installation problem


Your reader/writer is set up for use on 2 USB ports (hence the 9 pin connector), one port for the reader and one for the externak USB port. This has nothing to do with the port version. The long and short of it is you need a card with a matching internal header. NEVER break off a pin! Some of these headers have reversed connectons so you probably broke of one of the data pins and runed that header's ability. Typically the readers like you have come with several cables, so that they can match the headers you have available. Older motherboards and add on USB cards did not use standardized header configurations aas you seem to have found out. Your best bet at this point is contact the manufacturer of the reader and find out what brand of add on USB cards they recommend and go with that. AND AGAIN NEVER REMOVE ANY PINS FROM A HEADER !!!

How to install a sd card reader on a Dell Dimension 8200 PC Desktop? no 4 pin usb on motherboard?


I managed to install a card reader on my Dell Dimension 8200.

The main problem is that the Dell motherboard does not have the correct USB pin. This is a 9-pin MoBo USB header.

The quick answer is I installed a USB card with an internal port.

http://www.amazon.co.uk/Unbranded-USB-2-0-PCI-Card/dp/B00066LPA2/ref=sr_1_6?ie=UTF8&s=electronics&qid=1264968643&sr=1-6

Secondly I reverse mounted a powered 4-port USB hub in the spare 3.5" bay.

http://www.cablecity.co.uk/product_info.php?products_id=1149&ref=6


Third, I purchased 2 USB 5 pin male to usb leads...

http://www.amazon.co.uk/v2-0-Male-Motherboard-Header-Connector/dp/B000QC7NKM/ref=cm_cr_pr_pb_t

You cannot buy a USB card with 2 internals and do away with the 4 port powered USB hub because the card reader does need to be connected to a powered USB port.

Black monitor no power


Hi. On some motherboards the 'Enable usb Support' option in system can cause this. Use a conventional ps2 mouse and keyboard, unplug all usb devices, enter system and ensure that 'Enable USB Keyboard Support' is turned off and continue setting up as usual. Try locating a bios upgrade for the mobo concerned.

I hope this helps. Let me know how you get on.

Tower top mounted USB portss


The cables from the front panel USB connectors have a key in them that will line up with the missing pin on the board's USB headers. Just line up the connectors and plug them onto the board. It doesn't matter if you use USB1 on the board for the plug marked USB1.

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
