Arduino set up for work with Octave (Matlab) then disconnected

Hello everybody,
I just set up Octave for work with an arduino.

arduinosetup worked fine.

scanForArduinos yielded

[1,1] =

scalar structure containing the fields:

  port = \\.\COM4
  board = uno


But a=arduino just gave me the error message

a =
arduino object disconnected

And a new scanForArduinos didn't find any.
I tested several boards on both USB ports of a Microsoft surface 7 running Win10.

Has anyone encountered and maybe solved this problem?
