In a recent review of the Soyo P4S Dragon Ultra Mainboard
it states that it does support USB2.0
I assume that other boards with the sis645 will also.
This site links to some (many) SIS645 reviews. http://www.sis.com/whatsnew/645reviews.htm
I have the soyo ultra and the sigma breakout box is embossed with the legend USB 2.0 .. I have no way to confirm this .. The mobo also shipped with a coupon for a free USB PCI card .. sent for mine but don't expect to get it until I have long forgotten about it lol.. the mobo box state it is usb 2.0 too but I wonder .. does anyone know of a test that can determine this ? ( didnt see it in sandra 2002 .. did I miss it ?)
