Is the Forum tip not showing? It reads "Tip: If you are asking for help to troubleshoot a computer-related problem, please be sure to include all the necessary information (ie: operating system, model number, hardware, software, etc) that will help others identify your problem for a speedy resolution."

Some OSes don't do USB 2.0 but you can read http://www.usbman.com for the usual insight on that.
