Help with GA-X58A-UD3R motherboard

[amron]

Hi, will appreciate your help. I have a GA-X58A-UD3R mother board. of course I've downloaded it's manual and as far as I can see, in the manual shown two USB headers while on my board there are three USB headers, one red and the other two light blue (pic attached). could you please shed some light for me explaining what is the difference between them?
if it's a newer version of the board, I wonder why Gigabyte doesn't publish an updated manual.

Greetings,
The red port supports on/off charge. This micro site describes the feature.
