I just got a case that came with the Blue USB 3 header to motherboard, but it also has a very short usb 2 header on the same cable. When I plug the USB 3 to motherboard, the USB 2 Cable is unable to reach any ports. My question is, do I need both plugged into the MB in order to get both USB ports on the case front to work, or will the Blue USB 3 plug work for both case ports? (1 USB 2, 1 USB 3).

Thanks

i would immagine the usb2 header is incase your mobo doesnt support 3 and you use either or, but im not sure. i'd have to see how much of a split there is between the headers and maybe know what case it is.
