One of my colleagues, who is studying networking in college told me that US b ports were very sensitive and that I needed to use remove USB device from the system tray. I plugged in the Bookport when I booted up..and it worked!! I used the remove USB device, before shutting down. When it worked the bookport software came up automatically. Hopefully this has solved the problem. My colleague said that US B devices were very sensitive.
