i just bought a new case at COMPUSA and it has 2 USB ports on front of the casa with the wiring to connect them. on my mobo there is an extra USB header that has 10 pins arranged in groups of 2. now my question is, are those pins meant for 2 ports or 1? the wires from the case only cover 1 pin per USB port, are they supposed to cover both pins on the mobo?
