New case, how to get front USB's working? (Cooler Master HAF XM)

[jackson10t]

So I just bought a new case (Cooler Master HAF XM) and it has four USBs in the front, 2 reg and 2 usb 3.0. I know this seems a bit rookie, but how would I get these to work? I honestly have no clue where I can plug the case's usb plug-ins into my motherboard. I included some pics, please help. thanks!

MB: GIGABYTE GA-H55M-S2H

Try the blue ports beneath the lowest PCI-E slot

lol! my graphics card was covering it. -_- But thanks! I just moved my GC up a slot so it can fit. But how about the usb 3.0 port? I dont think my MB is 3.0 compatible, but is there any why I can just plug it in so i can use it for regular usb? I included a pic of the slots and the input for the usb 3.0 ports. Where can I plug it in at? Thanks!!
