Q: My motherboard is SiS chipset based K7S8XE, why my USB 2.0 hard disk box can not be recognized under Windows XP?(11/14/2003) A: We have experienced that some USB 2.0 boxes may not conscientiously follow the USB 2.0 specification to design, so it cannot operate properly with USB 2.0 specification. Please update the newest BIOS, and then disable the USB 2.0 controller in the BIOS SETUP. At this moment, the USB 2.0 box may have chance to operate with USB 1.1 specification.
