Scott is right, USBs arent vital unless you have stuff that you rely on them for, i.e. keyboard, mouse, webcam

if the hub works fine theres nothing to worry about if the other 2 ports go so that the hub can no longer work i suggest either going to regular analog mouse and keyboard or you may have to get a new motherboard (i know its stupid new motherboard for USB ports)

on a side not, i almost died when i saw the works pam and build in the same sentence
