Hi Jim, Yes, I had this very same issue with my new Book Port a couple of weeks ago. I have the Book Port Transfer program installed on my IBM Thinkpad. I have a powered USB hub, and was connecting the cable to the hub. In my case, the problem was resolved when I connected the cable to one of the notebook's USB ports, rather than using the hub. I wish you well on this one, as it drove me crazy, until we found the solution. Crystal
