I own a Dimension 4400 which i purchased in Dec/Jan 2001/2002. It has 4 USB ports and I assume that they're 2.0.

 

I have an external hard drive, but when I turn it on, Windows tells me that I don't have any Hi Speed USB ports on my computer. In my BIOS, it says that Legacy USB Support is enabled. If i disable it, will I be able to attain Hi Speed instead of legacy 1.1 "Full Speed"? Or are the ports on a Dimension 4400 incapable of Hi Speed data transfer rates?
