Det är lite rörigt det här med USB, men 3.0 är uppenbarligen samma sak som 3.1 gen 1.
"USB 3.0 was released over ten years ago in 2008 and it was the third major revision to the USB standard. It was a big improvement from USB 2.0 which first arrived in 2000 with transfer speeds of only 480 Mbit/s. Since then, we’ve moved on from USB 3.0 which is now known as USB 3.1 Gen 1. Therefore, USB 3.0 is the same thing as USB 3.1 Gen 1."
