I have a Compaq Evo with windows xp. I just got it today and I thought everything worked fine until I tried to plug in my ipod into the USB drive. I did not buy this new, and I cant figure out how to fix the problem. Can someone please help me. I really need to use my USB ports. I checked the device manager and there is nothing that refers to the USB ports/drivers. I really need some help please. Thank you
