It is a standard mini USB cable. One end is regular USB and the other is mini USB. My USB that I have for my bp fit into my standard MP3 player, my Motorola Razor phone, and my I.R.I.S pen scanner. Hope this helps. ----- Original Message ----- From: Scott Huddleson To: bookport@xxxxxxxxxxxxx Sent: Wednesday, February 07, 2007 4:14 PM Subject: [bookport] USB cable Walt, I'm not sure at all about the different connections used with USB cables, but in a previous email, I listed from the manual what type of cable was used. . 4 ' USB A Plug to 5-Pin Mini-B cable. I got this information from the list of "what's in the box." was this an error by APH while developing the manual? I only ask because I buy almost everything on line since I live out in the middle of nowhere. If I were to go to a store, I would just take the cable with me. The descriptions on Radio Shack';s web site are not usually very helpful if you are trying to figure out if the particular cable or connector is the one you want. Take it easy, Scott
