 It's possible you have bad USB ports, a defective motherboard, or a defective drive.  .

 I haven't had trouble with my usb ports till now. I run my modem, camera and scanner out of them. I wonder if perhaps it can't use them since they are devoted to what I already have, but the modem and scanner share the same port with no trouble, except I have to swap leads depending on what I use.
