Someone didn't do a proper job with his homework USB3.1 comes in two flavours called Gen 1 and Gen 2. Gen 1 is better known as USB3.0, Gen 2 is the "actual" USB3.1 with the 10Gbps bandwidth and being able to supply power up to 100W. The real question is...which USB3.1 do the manufacturers and OS makers (in this case Microsoft and Apple) support? I doubt that at the moment anyone supports USB3.1 Gen 2 simply due to the fact that it isn't freely available yet. USB3.1 Gen 1 is (quite obvious as this is just USB3.0 which has been supported for quite some time now).
