I'm sorry to trouble y'all, but we have some major geeks out there. I'm wanting to buy a TV tuner for my notebook and most say you have to have USB 2.0 for them to work properly. I've been all through Control Panel and can't find what my version is. How would I locate that? I am on a Dell Inspiron 2650 running Windows XP Pro. Any hints? Thanking you in advance!!!
