motherboard/case and getting USB ports to work

This question applies to a lot of motherboards and cases... and it is not answered by the manuals... this has happened a few times to me... a case will have a front mounted USB port with two or so connections, but each connection will have its own cable with 4 small female pins... the motherboard connection will have only 7 male pins... the additional pin is usually a ground... is there a way to get this to work?

I have not troubleshot this too much... one time the computer would not boot so I just unplugged it and hooked up the rear ports... anyone know what I am talking about here...

I have to teat apart my computer tonight to replace a north bridge heatsink/fan on an NF7-S anyway, so I thought i would try and get the fron USB ports working... I could tear out the ABIT USB slot insert and attempt to mount it in the front, but that would be a pain...

More about motherboard case ports work
  1. Most cases (or at least the ones I have bought) come with documentation on how to go about connecting the front panel USB/Firewire/audio ports. As well as your motherboard should contain the pin-out for your extra USB connection(s). The other option if having a USB port in the front is simple, go to an electronics retailer (bestbuy, walmart even)and grab yourself an extension cable.
  2. No. Standard motherboard USB headers have 9 pins, the 9th and missing 10th pin are redundant grounds. That means the top row of 4 and the bottom row of 4 correspond with the wires from the case.

    There are no USB headers with only 7 pins, you miscounted one column.

  3. You are correct, of course. I meant 9, not 7. but I have 10 female connections to place on the 9 pins.

    So, I really do not need either 9 or 10. That is good to know.

  4. there is 2 USB ports for one connector. You need 4 wires for one connector so two rows for 2 sets of 4 wires. usually, the red is power and black is ground. green and white are signals wire. So, if you look at your manual, find the + pins and start with red,white,green, black. the fifth pins is another ground, the fifth pins is not really used, it is a common ground.. I dont know how to tell that in english.. I have a memory hole

    -Always put the blame on you first, then on the hardware !!!
  5. I already had then lined up correctly with some tape around them to keep the connectors in position... I was just concerned about the extra pin... I got it working no problem... and now my north bridge is being cooled again... so pushing my bus above 210 at the moment... thanks all...

  6. The forth pin on both rows is ground. The fifth pin on one row and the missing fifth pin on the other is a redundant ground, normally used to ground the case to the board. This redundant ground can be a shield wire used to prevent EMI from interfering with the data. You should have at least 1 of those hooked up, but many cases don't even supply the redundant ground (in which case the manufacturer feels it's not needed even if the rest of us believe it's desireable).
