I am interested if others have the same issue or if I have a device with additional hardware errors. I received my device four weeks ago, it has the factory system (Byzantium) with all available updates installed.
If I insert a sd card nothing changes, the card can’t be accessed. Some outputs (which are always the same no matter if the card is inserted or not):

There is no additional entry when or if the micro sd card is inserted.

Here is what gnome disks shows with inserted card:
Which is the same no matter if the sd card is in or not. I have tested with several sd cards (Samsung EvoPlus, SanDisk Ultra) all of them working flawlessly on all other linux machines.
In my opinion this seems to be a hardware/power issue. Maybe the cardreader isn’t powered or correct cabled? Maybe the contacts between card an cardreader are not correct?
Can anyone confirm this behaviour or help trouble-shooting? Thanks
