My idea was eigebtlich to connect via USB mouse and keyboard, screen mirroring via a monitor to control, and load my tablet at the same time - so it would be a annhmbarer desktop replacement for browsing and video Play been. Unfortunately, the simultaneous charging but not funtioniert, so a battery charge vielleuch is just enough for a film (Screen Mirroring is battery technically quite expensive). USB is suf on Tabet definitely good, but I can not forgive more than 3 stars.
