Windows 7: Internal 9 pin usb header to male usb 2 plug?

alphanumeric · 18 Feb 2012

Keep in mind that what I posted is the header on the motherboard, not the plug on the end of your cable. If you look at your plug from the back, where the wires go in, it should match up. If you look at it from the side with all the holes in it, it will be a mirror image. If your plug only has 4 wires in it, you only need one USB cable. If it has all 8 then you likely need to use two. You might get real lucky and just have to match the colors of the wires, Red, white, green, black. Unsolder them one at a time, swap wires, re-solder.

Thank you very much, yes, I had thought about that it being a mirror! The ninth slot should help
me orientate it though. I have found that there are 8 cables. I don't think they are colour coded though. So looks like it is going to be two USB plugs then. Thank you very much for your help everyone, much appreciated!

I have just got a reply from my friend, they are colour coded red, green, black an White. It shouldn't be too hard then! Now have got to fork out a pound to pay him for the card reader lol!

Music Guy.
Sorry I just found my way back to this thread. But I see you are getting more than enough help here already.

Yes, mostly USB cable are color coded as you can see here,

But in making new connection, do not rely on it. You have to personally find the way to make sure you connect the right cable (instead of color) to the right pin at every step. More, to avoid losing the way, cut only one cable on every step also. Confirm it with available Ohmmeter (multimeter)
Here is the clue,

Do notice that the "ground" pin is close to the blank pin (on the 9 pin assembly). No 4 on the pict.

Hope it give you more ease to work it out

Thank you very much for that, the colour chart especially was very helpful. I am sure I will be fine, I know what each of the slots in the header are for so will probably check the colours and if they are right, will cut it 4 at a time, do one plug at a time. Thank you all again, I think I have got it now! When I complete it, will post again with pics! Thank you all very much.

When you can go out and purchase a usb card reader for under 10.00usd I'm not sure this is much more than an opportunity to learn, but to me the one wrong move would have me wondering why I toasted a mobo for a card reader.

True but, I can get a 52in1 memory card reader for 1 UK pound. That is nothing! It is well worth the try imo! I don't think it will toast the mobo, infact, it will probs do me a favour lol!

If you get the Data + and - back wards all that "should" happen is you get a "unrecognized USB device" or similar message. USB ports are overload protected but I still wouldn't want to test getting the +5V and Ground leads reversed. If you did I would expect the card reader to suffer the consequences not the motherboard. I'd still be careful, its been my experience that what you think should happen, and what actually does happen are often two different things.

Music Guy123 · 19 Feb 2012

Haha, yeah, that is true. If the card reader does get damaged, hey, £1, not a great deal. If it works well...hooray. If it fails, I would have thought the worst thing that could happen is the USB contoller gets damaged do you think or would it damage the whole mobo? I guess if it does fry the mobo, at least it gives me an excuse to get a new lappy :P !

Its hard to say what will get toasted if you botch the wiring job. I know if I was doing it I would want to be doubly sure I got it right before I plugged it in.
