Hi, I do not know, why there is a problem with the connection of the external dvd writer. The conection to the USB port to the keyboard was unsuccessful. Chuwi Hi 10 X does not see the dvd writer. Then I connected ext. DVD writer through the adapter to the USB Type C 3.0. port directly to the tablet. Now the ext. DVD writer is there, but the picture is cutting itself and the ext. DVD writer cannot run properly. In the PC the ext. DVD is working normally. Teerem
