This card works great if you need some extra USB ports. I bought it becuase I needed some extra USB ports for my scanner and printer. I have a dual-booted system with Windows 98SE and XP, and it worked flawlessly on both without the need to install drivers. All you have to do is plug and play!Only problem I have is that the card only has 4 ports. It may be advertised to have 5 ports, but the 5th port is internal rendering it almost useless. That aside, the card runs very well.Since I updated my PC I no longer need this however...
