From the ECS K7S5A FAQ

The K7S5A has a header for connecting two extra USB ports, but you need to buy an extra cable. The cable should have two USB ports on one end and a motherboard connector on the other. You also need to know what each pin connects to:

1 --- 2 Red (+ 5V)
3 --- 4 White ( -- Data)
5 --- 6 Green ( + Data)
7 --- 8 Black/Gray (Ground)
9 --- Black/Gray (Ground) or not connected
