case= NZXT H510We're going to need more information than one line and a thread title. What is the make and model of your case? Can you parse an image of how you've connected the case's USB header to the motherboard? I'd also inspect the pins on the motherboard's USB connector in case they are bent or broken. As for the ports, are you sure you installed the chipset drivers for your platform? Doe the rear ports work?
