The USB connection has been around for a few years now and it's evolved into version 2.0, then 3.0, then 3.1 and I don't know if there is one newer there version filed there. But these USB drives are relatively slow by today's standards and have a small capacity of 2 GB. It was a great memory a few days ago, but not anymore. I got what I paid for, can't complain!
