Quick question: What is the difference between USB 4.0 and USB 4? And what is "USB 4.0 USB4"?
@Fernando
USB 4.0 should have been the assumed name given to the next USB revision, but for some reason they are trying to call it USB4 which does not follow the pattern they started. In the future people will be using both USB 4.0 and USB4 when describing it because of this mess. Which name do you prefer? Vote.
