Here is the link to all the info about the Kindle Fire. Page down to see a chart comparing it to other Kindles feature by feature which is good for showing exactly what features it has. It looks to me like it does have a USB. I wish it had 3G. My daughter said her and my son are getting it for for Christmas.
