Hi,I just installed a nexxtech 7 port 2.0 usb hub,and now when I use my printer up pops this"You must add a hi speed usb host controller to this p.c. to obtain max. speed." Can someone simplify what is necessary here. My cordless mouse,netmate link and printer are all that runs off of this usb hub. WXP/pro/sp2 800 mhz.
