What in the world is going on here? I just got a brand new G15 Logitech gaming computer and a brand new Logitech USB mouse as well. I have a total of 6 USB ports on my CPU, 4 on a secondary device (not 2.0), and 2 in the back of my new G15 (also not 2.0). Yet I can only use one of them? Is this a power overload? What could be the problem, here? If you have any questions, ask away. It's very annoying, thanks in advance if you have any idea.
