ECS K7VTA3 ver.8 has full USB2 support.
Some thoughts about enclosure.
CD burning @52 is 52 x 150kb/s = 7,8Mb/s. Burning DVDs at 4X (5,4Mb/s) is no problem. Not sure about 8X.
Remove any 'old' (CD) drivers in devicemanager, restart the comp and give it a try. At boot-up XP will install what you need, though.
[The enclosure must be powered.]
