Tiffany, I'll assume that with all these usb devices you must be using a usb hub. If so, are you using both ports for the computer? Have you tried removing the hub so that the Bookport goes directly into the computer? I once had a problem with a device, a usb device of course that couldn't be plugge dinto a hub or it would refuse to function. Just an idea and I can't recall anyone asking about a hub. Scott
