I have an old "Dell by Microsoft" keyboard and a Belkin extension cable that I have been using for years without problem. I just got a new Dimension 8400 along with a new basic Dell quietkey keyboard. When I try to connect the new keyboard through the extension cable, the keyboard doesn't respond at all. The 3 indicator lights just blink constantly and the keyboard doesn't work. If I connect the new keyboard directly to my PC then it works fine.

Does anyone know what I need to do to get this to work? Do I need a different type of extension cable? Or did I get a keyboard with issues? Does anyone else have this type of setup working?
