Lately when I connect my iPod to my Mini I'm getting the error message that my iPod "is connected to a low-speed USB 1.1 port. For better performance, you should connect it to a high-speed USB 2.0 port, if one is available on your computer." I can't figure out why this message is suddenly appearing after a year of normal connections (using the same port every time) with no such notifications. Is this a common glitch? I'm running iTunes 10.3.1 and Snow Leopard 10.6.8.
