for kjacobs, looking at the menu of Asus P5A-B, there are no "2nd"USB, its the first and only one, right?
They might has a module connector for USB,Infrared, PS/2. But i guess it is not easy to find and costly.
Your layout is
pin
1_________2__________3__________ 4__________ 5 .......
usb +5v....... usb port 0-.....usb port 0+......ground......... (no connection)
10________11_________12_________13__________14
usb +5v....... usb port 1-.....usb port 1+......ground......... (no connection)
+5 ->red
- data ->white
+ data -> green
ground -> black
(no connection) -> left out or connected to shielding of the USB cable
So it is basically the same as K7S5A.
But i must give a WARNING here that the color of the wire meaning nothin as my exp. with my K7S5A teach me

I wrongly ordered a 2X8 from
www.mjpa.com $3.99 (should order the 1X4, what was i thinking....). And their wiring is totally reversed! (Red => ground, white =>+data,...), i ordered it with other things for a 12v/off/7v fanbus project, which turns out very well.
So the sure thing is use mutlimeter to ensure the USB connector (the one that connect to you USB mouse, scanner ) has the following, looking from outside toward it:
[ 1...2...3...4] <----- this is the metal inside the USB connector
_________ <---- this is the white separator
where
1 = ground, (or usually connected to color wire Black)
2 = + data, D+ (or usually connected to color wire green)
3 = - data, D- (or usually connected to color wire white)
4 = 5V (or usually connected to color wire red)
So if the one come with Epox 8kHA+ match it. you can.
i can not get the layout of the epox 8kha+. sorry can not tell you for sure... (what site it is epox.com? this site is inaccessible thro my co. internet, i try 2themax.com and they do not have menu)
