usbhub20.sys not included in Windows XP sp2

I'm trying to get my Targus USB 2.0 hub to run at USB 2.0 speed.
Everything I've located on the internet indicates that Windows XP
service pack 2 should include the necessary files to install it at 2.0
speed. It always installs intself as "Generic Hub" instead of "Generic
Hub on a 2.0 bus" which is what it's supposed to do. I searched my hard
drive for the drivers but usbhub20.sys doesn't exist.

Anyone have any suggestions?
Thanks.

Actually usb 2.0 comes with xp SP1,SP2 also has it as it includes SP1.
You can open device mgr in system properties,scroll down to the usb
controller,R.click,select update drivers,xp will load them.If you have an
intel based board,go to intel first,download and install the chipset inst-
allation utility,then after proceed to device mgr.
