Trouble getting my DM41X to be seen by windows11

[rprosperi]

The problem is nearly certainly to be an improperly connecting cable, there are few other things that can go wrong, no drivers or special s/w is needed for the USB mode connection. Is it possible the cables you are using are charging cables and don't have signal connections, this is also a common situation. Can you connect (beyond power) to other devices using the cables that seem to not work with the 41X ?
