Solved Can't instal USB ports

April 11, 2012 at 11:23:05
Specs: XP Pro, Athlon 3400-4gigs ram
Mother board has pins to instal 4 USB ports on front of computer. Problem is, the wires are labeled differently than the instructions in motherboard manual. Example, pin #9 calls for the wire labeled ground. Working from pin #1 to pin #9, I have already used all my wires labeled ground on the lower # pins, as per motherboard instructions. I use the example "ground wire" because it was easy for me to remember. There are 2 other instantsess with the wires being labeled with other words, that just don't correspond to what the motherboard instructions call for. I have been using trial & error trying to get the correctly labeled wires to match up with pins on the board, but with no luck. I'm slightly better than a complete novice, having built my computer from scratch, but this has me baffled. I'd really like to get the USB ports on the front to operate as they should, it's a pain crawly on the floor to load my flash sticks into my computer. Can anyone offer some help please. Thank you in advance.

JUSB2/JUSB3

USB header - it's the same situation as for many recent mboards. E.g. Recent and fairly recent Asus mboards have the same USB header, pin arrangement, pin numbering, and designated pin uses.
It's the most common situation for a USB header on a mboard these days.

All odd numbered pins on one side - 1, 3, 5, 7; no pin at position 9

KEY is usually = no pin there.
Some one piece double row wiring connectors for USB ports have a blocked pin hole at that location, so in that case, the connector can only go on the pins one way.
However, the wiring uses of the connector at each pin hole MUST be compatible with the USB header's wiring otherwise. In your case, both rows have the wiring in the same direction - the +5v wires must be beside each other at the positions for pins 1 and 2, etc. .

NOTE that it causes no harm if you connect the connections for Data - and Data + backwards, but if you get the connections for +5v and it's Ground backwards, you will probably FRY the circuits of whatever you plug into the mis-wired USB port, instantly, if the computer is running at the time !

All even numbered pins on the other side - 2, 4, 6, 8; pin 10 has no connection to the mboard
NC = No Connection, to the mboard USB circuits


In this case in your Biostar manual for your mboard ...

USB - a.k.a. Data -
USB + a.k.a. Data +

As I said above....

"The USB headers may have all odd numbered pins in one row, all even numbered pins in the other row, or be numbered in sequence in each row, e.g, 1 to 5, 6 to 9.
The list of uses for the pins in the manual is usually listed 1 to 9 in any case. For the first situation, heed only the odd numbered pin uses in order for the the one row, only the even numbered pin uses in order for the other row. "

Connect the wires for one USB port to pins 1, 3, 5, 7 in one row.
Connect the wires for another USB port to pins 2, 4, 6, 8 in the other row.

You don't need to connect the fifth wire for one USB port (or for a ground for the outer metal shell for both ports) from the case to the USB header - even if you did connect to pin 10 it isn't connected to anything (NC = No Connection) .
If you have three ground wires from the case, it doesn't matter which two of them you connect to pin 8 and pin 7.
If you have two grounds from the case and a wire for OC, do NOT connect that wire to pin 8 or pin 7.

If the case has individual wires, individual wiring connertors for each wire
- the characters printed on the connectors have a number indicating which of the two front USB ports it is for - e.g. 0, and 1, or 1, and 2
- or - there is no number but the wires for one USB port come from the same cable sheath, or the same bundle of wires, the wires for the other USB port come from the other one.

A generic case may have a label stuck to the inside of the case that tells you what each wire for the front USB ports is for.

Hi tlewis, it would probably help if you advised:-

a) make and full model number of the mobo

b) pin definitions given in the manual

You could probably use the edit function on your above post for this.

Good Luck - Keep us posted.

There are only 4 wires in a single usb port 1 Vcc(+5v) 2 D-(Data-) 3 D+(Data+) 4 GND (Ground) Colors are usually Red White Green Black. The 5th wire is the shield.
Pin 9 is the shield. One shield per paired port. The pins are usually in order.

We need "make and full model number of the mobo"

The USB headers may have all odd numbered pins in one row, all even numbered pins in the other row, or be numbered in sequence in each row, e.g, 1 to 5, 6 to 9.
The list of uses for the pins in the manual is usually listed 1 to 9 in any case. For the first situation, heed only the odd numbered pin uses in order for the the one row, only the even numbered pin uses in order for the other row.

Sorry, could not find any edit option to my question. Thanks for getting to my question. There are some very smart people on this site. To get to the info you requested. Mother board is a GeForce 6100m9.Pin assignments are: #1+5v..#2+5v..#3usb-..#4usb-..#5usb+..#6usb+..#7ground..#8ground..#9key..#10nc.........Some of the labels on the wires match these, some do not. There are 2 rows of pins, 1 of the rows is all odd numbers and the other of course is all even number pins, for a total number of 10 pins.The wires are labeled with things like +D..-D..and they each either have a prefix of the number 1 or number 2 prior to the letter designation. These wires are suppose to allow me to use the 2 usb ports on the front of my case.There are a total of 9 wires coming from the ports. They have labels like this. 2 says +5v, 2 says-5v, 3 say ground, 2 say +d and 2 say-d. I hope I haven't confused you. Thanks again, looking forward to hearing from you soon.

Thanks for getting to my question. None of the pin assignments according my manual designate +d or -d. Book says pins are as follows: Pins one and two are +5v...Pins three and four are USB(-)..Pins five and six are USB(+)..Pins seven and eight are both ground..Pin nine says "KEY" and pin number ten says NC...My wires are labeled as follows: 3 say Ground. Two say (+)5v, two say (-)D and two say (+)D. There is no place for the "D" designation to go according to my manual and none of the wires are labeled either USB (+) or USB.(-) and I'm suppose to have 2 of each. Confused!!

Thanks Fred for getting to my question. I have the wires labeled (-)D and (+)D as you said, problem is my manual does not mention them. The 10 pins are suppose to be attached like this: one and two pin is suppose to be +5V, three and four pin are suppose to be USB(-), five and six pin are suppose to be USB(+), seven and eight are suppose to be both Grounds, nine pin is to be "KEY" and the number ten pin is "NC". I have a total of 3 ground wires, nothing that says NC or KEY, nor do I know what their abbreviations stand for..Does this info help you any??By the way, my board is a GeForce 6100m9. I think its made by Biostar.

Look:
http://www.newegg.com/Product/Produ...
This front USB bracket uses a single piece plug in connector for your motherboard (common) that just plugs into your motherboard and powers up two USB ports and mounts into an external drive bay.
If you click on the picture you will see an enlarged pop up of the picture with additional pictures and if you click through them you will see the plug that would go into your motherboard. All of my cases came with similar plugs so this was not any trouble. If yours did not come with this and you continue to have trouble sorting this out, you may want to consider one of these front brackets that appear to be easier to use than what you case was supplied with.

You have to be a little bit crazy to keep you from going insane.

Fingers, thank you for sending the pictures and product info on the USB mounting bracket. What a great idea. Since reading your post to me, I've been going over my motherboard's schematic and I can't find any pins that would allow me to hook up the ports using a single cable on my board. This would have been a perfect solution if I could've done it this way. Thank you very much for your time and consideration for my problem. I'm thinking about trying to use the pins labeled USB (-) and USB (+) by using the D (-) and the D (+) cables since the way my wires are labeled, they just don't match the board. Do you think if I tried this I could possibly do damage to my motherboard if it doesn't work?? Thanks again. I've been really impressed by the knowledge and responses I've received on my problem. Wish I would have known about this site years ago. Probably could have saved me many sleepless nights, self teaching myself about what makes these computers click. Lots and lots of trial and error on my part.

NOTE that some mboards, e.g. at least some Asus models, have a header for a firewire (IEEE 1394) port that is physically identical to the header on the mboard for two USB ports.
The plastic below the pins on the firewire header is usually a different color than for the USB header(s).
If you connect wiring for USB ports to the firewire header, or the wiring for a firewire port to the USB header, there is no problem if there is nothing plugged into the mis-wired port, but when you plug something into that port, all hxxx breaks loose ! If the computer is running when you plug something into the mis-wired port, you can damage the circuits for the header on the mboard AND damage the circuits of whatever you plugged into the port instantly, or in a very short time, and the mboard may be otherwise damaged !

Hello again. Your suggestion and my lucky guess worked as far as getting my USB ports to work on the front of my box. I did get a message at start up that was a surprise though. It said the sticks that I had put in the ports were high speed, but the USB ports are not. Then it went on to say something about I move the ports to get better performance. Don't have a clue about doing that. I want to thank you again for your help. It's nice to know there are still people in the world that will give their time and effort to assist a stranger. Can't tell you how nice it was not to have to crawl on the floor to put those sticks tonight. I don't know why the thought of using the usb(-) and (+) as the data markers eluded me so long.The plus/minus should have tipped me off sooner. But hey, all is well now. Thank you again!!

Not all front USB ports on cases have wiring that supports USB 2.0 specs, but the USB ports built into the mboard always do, if the mboard supports USB 2.0 specs.
You can have problems with any device that's plugged into any USB port that's not a physical port built into the mboard.

Troubleshooting USB device problems
See Response 1:
http://www.computing.net/answers/ha...
......

If the wiring of the front USB ports DOES support USB 2.0 specs....

"It said the sticks that I had put in the ports were high speed, but the USB ports are not. Then it went on to say something about I move the ports to get better performance."

Assuming that the USB controller settings in the mboard's bios Setup are set to their default settings and USB 2.0 support has NOT been disabled there....

You are getting "nag" messages when a device such as a flash drive that informs Windows it supports USB 2.0 specs is plugged in because the USB 2.0 support HAS NOT BEEN INSTALLED yet.
(If that has not been installed, you will get the "nag" message for ANY device that informs Windows it's a USB 2.0 device when it's plugged into ANY USB port the device works properly with.)

Windows 98 and above installs support for USB 1.x controllers and devices automatically (if the USB controllers are enabled in the mboard's bios Setup, which is always the default setting) , but it does NOT install the support for USB 2.0 controllers and devices automatically.

When your mboard has USB 2.0 controllers they're backward compatible with USB 1.1 specs.

On some older mboards, they have some USB 1.1 ports and some USB 2.0 ports, but in the case of your mboard model, all USB ports support both USB 1.1 and USB 2.0 specs.
....

When your mboard has USB 2.0 controllers....
(or - when you mboard does not support USB 2.0 specs but you have installed a USB 2.0 controller adapter.....)

- XP must have SP1 or later updates installed in it in order for it to have built in support for USB 2.0 controllers and USB 2.0 devices

- you MUST install the main chipset drivers for the mboard after XP's Setup is finished in order for that built in support to actually be installed in Windows for the mboard.

Also, you need to install IE 8, and install SP3 updates if they're not built into the XP CD you used to install Windows
