Dead USB-C on my Alldocube Knote 8

Hi guys, i think that my single USB-C port on my Alldocube Knote 8 is dead…. When i plug in some USB disk, nothing happens, no one error message, just nothing. I tried different USB-A to USB-C adapters, i tried different USB devices, nothing work. I also tried to re-install drivers but it does not help me. Is there any chance, that USB-c port is dead? And is there any chance to fix it or replace it? Thanks for any answer
