Query: Doesn't work

I tried to use the USB hub by Linksys and when I did the screen would freeze or my track ball orkeyboard would not work properly. They work fine when disconnected from hub. I am using withWindows XP Professional on a Dell laptop. I called Linksys and was on hold for 25 minutes. I hung up.Again I called and was on hold for 15 minutes then when they transferred me I was disconnected.
