High speed usb device vs non high speed hub

when i connect usb mass storage device to my usb port a message pops up,
"this device can perform faster if you connect it to usb 2.0
port.............click here" If I click this baloon:

a window with my usb drives listed comes and says to add hi-speed usb host
controller to obtain maximum speed.

The list says:
1- Intel 82801BA/BAM USB universal host controller 2442
2- same as above but 2444

How can i add host controllers to make my ports 2.0? I am using XP provided
