I recently bought my new macbook pro 2017 model which comes with USB Type-C ports supporting thunderbolt 3 standard with USB 3.1 standard. So since I have lots of devices with USB A type and supporting USB 3.1 standard, thought to buy some adapters. But when I'm shopping to buy them I saw that most companies have claimed that their USB Type C adapters are supporting USB 3.0 standards instead of 3.1 and couldn't find any adapter (which satisfies my needs) supports USB 3.1 standard. I was kinda confused now and have to problems to solve before buy them.
1) Since my devices supprt USB 3.1 and Macbook supports USB 3.1 standard, will those adapters (which claim to work fine with UBS 3.0 ) deliver the speed of USB 3.1?
2) Those companies have claimed that those adapters are working with USB 3.0 standard because USB 3.1 is quite young?
