Nintendo switch USB not recognised on PC or other devices

Hi there, I’ve got a Nintendo switch that charges fine, but doesn't react at all when connected on USB devices like dock, computer or payload injector (jig). I've got 3 more Nintendo switch and they all work fine with the above devices. So far I've tried to replace the USB IC and 4 different charging ports but nothing has changed. Do you guys have any idea on what I could try next? Thank you!
