If you review the most current boards spec. from August 2001 http://www.intel.com/support/motherboards/desktop/d845wn/sb/cs-008943.htm page 20
you will find this mother board has only USB1.1 native.
You could add a PCI usb 2.0 card http://shop.ebay.com/?_from=R40&_trksid=p3907.m570.l1313&_nkw=pci+usb+2.0&_sacat=See-All-Categories
Completly agree with Doc, the only htings you can do is either get a PCI card or another motherboard.
Hmmmmm ........ OK !
