Some potentially useful information:
I am running Vista SP1 x86
I know the issue is not the physical USB ports because my usb flash drive works at 2.0 speeds.
Before reformatting the external drive functioned at USB 2.0 speeds
I've ensured my computer is free of viruses, malware, etc.
I had problems with vista assigning the wrong driver to a USB mouse, which I was able to fix.
Thanks in advance.
