I have a Gateway 710XL tower purchased in 2003 (guess that makes it old). All of the USB ports (2 in front, 4 in back) are USB 1.0 and I would like to upgrade to USB 2.0. Can I do that with some sort of connection "card" or is that a function handled in the motherboard (MoBo) as my geek squad says? How do I go about upgrading? Thanks for the help.
