Hello Louis Eeckeloot,
I hope you are doing well.
Before programming and debugging your board, it is necessary to configure the device interaction with your computer. Could you please confirm you are updating the user EEPROM? Here you will find a post on how to do so.
I hope this information helps. Please let us know if you have any doubts or concerns and we will be glad to assist you.
Best regards,
Javier
