I guess I should say I think it is 2.0 since that is what is stamped on it. I bought it here thinking it was a memory stick but it is a card reader for the digital cameras that use the micro cards. I have never used them.
You plug in one of these into it and you can download the pics from the card to your computer. http://www.listia.com/auction/10317989-16gb-micro-sd-card
