No target management devices DS 3.6 (SL6087)

IoT Modules Development tools
2

I’ve added missing packages via the Packages Manager

Eventually I do see the device but it fails to connect with error

Open and load local port ttyACM0 => ERROR: Success
Open and load physical port ttyACM0 => ERROR: Success
Open port ttyACM0 => ERROR: Success
Wait for USB port to reconnect => NO NEED TO DO IT: Success
Open port ttyACM0 => DONE: null
gnu.io.NoSuchPortException
Pause : 1000 milliseconds => ERROR: Success

Am I still missing something?
