Can someone help me map the wires from my USB 2.0 connector to the pins on my motherboard?

The pins from the connector are labelled:
GND 2
GND 2
Shield
VCC 1
VCC 2
DATA +1
DATA -1
DATA +2
DATA -2

The pins on my motherboard are labelled:
(1) USBPWR
(2) USBPWR
(3) USBP2-
(4) USBP3-
(5) USBP2+
(6) USBP3+
(7) GND
(8) GND
(10)USBOC

Try the following connections:

USBPWR .... VCC 2
USBP2- .... DATA -1
USBP3- .... DATA -2
USBP2+ .... DATA +1
USBP3+ .... DATA +2
GND .... GND 2
GND .... GND 2

Dude, just line up the little arrows. Sometimes it's hard to find the arrow on the plug. The red wire is pin 1 and goes to the arrow on the motherboard. Companies have for the most part standardized the wireing order.

Crashman and elzt,

Believe it or not the usb 2.0 port on my PC case actually has 9 labeled single wires coming from it to connect to my MoBo. Each of the wires has a single pin-end connector on it that is labeled. Unfortunately, it did not come as one 9-pin plug

I do have another usb 2.0 port for my back panel that did come with a single 9-pin plug, but it was unlabeled so I couldn't learn from that.

PS: The mapping that elzt supplied appears to work (although I only have a usb 1.0 device so I won't really know for sure) Thanks very much!
