how to connect usb pins

[een]

Hope this is the right place to post this...

Now, my case has a front usb panel, and it supplies 9 connectors to be connected to 9 needle like thing on the mobo...

On the cable it says:
shield1
vcc1
data -1
data +1
gnd1
vcc2
data -2
data+2
gnd2

on the mobo:
power1
power2
usb dx-
usb dy-
usb dx+
usb dy+
gnd
gdn
nc

I can sort of guess, but I don't want to do anything harmful,

any suggestion is appreciated

What motherboard is this? Maybe the manual will have more useful pinout diagrams.

Things to try:

1) RTFM (for both products)
2) Call 1-800-get-help (er wahtever the manuf support # is)
3) Email Customer Service/Tech Supp at either or both companies
4) Go to http://www.google.com and search for your mobo and case and some relevant search string, ie: antec sx630 bm6 usb connection

the setup you described are for 2 port USB extention headers, you'll notice that there are 2 sets of the same cables just labled x and y. One is for USB port 1 and the other is port 2. It'll usually have 9 pins with 1 no connection one as a guide pin so you don't insert the factory header the wrong way.


It should setup like this

VCC1 -> Power 1
data-1 -> USB dx-
data+1 -> USB dx+
gnd1 -> grnd

VCC2 -> Power 2
data-2 -> USB dy-
data+2 -> USB dy+
grnd2 -> grnd

nc = No connection (just leave it empty)

I agree with HiTek21.

gnd
gdn

I hope that second one is a typo. If they are labeled grnd1 and grnd2 connect them to the same respective pair, as that probably keeps the power and ground closer together reducing the noise. If they aren't labeled plug them into whichever ground is closer. On the motherboard they are probably just connected together and then to the ground plane.

If you have any doubts do not connect it. You can fry your motherboard and possibly the device on the other end if you do it incorrectly. If you aren't comfortable bring it into a local shop and pay them to do it, if they fry your motherboard they can replace it.

Just match your colors according to the manual and/or the included USB-->PCI header.
That's what I do 😉

Black, green, white, red IIRC. If there's two grounds on the header, I ignore the one farther from the other colored pins, and my front USB is working well 🙂

With the smilies I hope that is supposed to be a joke. That is not a safe practice. The USB specs do not assign colors. I don't think I have even seen motherboard manuals list colors and even if it did, an engineer at one company may choose totally different colors than an engineer at another company. I have seen green, black, or white as ground. Power is often red, orange, or black. And unless stripes are used it is difficult to determine pairs of differential data lines and then one still needs to know whether the stripe is positive or negative.
