[rachid1997]

I want to buy a new dongle ’ At a price $ 50 ,
But I do not know how I can verify that the seller gives me the dongle with the third 3.0 version that supports the all-in-one interface .

In another sense:
How do I verify that when buying a new dongle it supports version 3.0 for all-in-one interface ?
