I just received my bookport yesterday. I installed the software on my computer and read the manual on how to transfer files. I tried to transfer some books to the bookport but the computer said that the Bookport wasn't attached.. The bookport was attached as I checked the cables. I also tried the 3 US B ports on my computer. I know they work because my US B memory drive works. After I unplugged the cable from the bookport the bookport wouldn't work..not even a beep. The only way I could get it to respond was to take out the batteries. Do you think the problem is the bookport or the cable? BarThanks!
