Many of the pins on the header are redundant. This is because NORMALLY you connect two seperate sockets to them, so each has it's own ground and +5vdc line, and each has it's own data wire. You're only going to use ONE of the two USB data lines which is why you only have 4 pins.

USE THIS WIRING:

+5vdc = verg_fp_usbpwr0 (either one, they're both the same)
ground = ground (either one they're both the same)
data+ = usb_fp_p0+
data- = usb_fp_p0-

BE CAREFUL!!!! Make sure you have it wired correctly or you can damage the motherboard.
