Calibration table update failed

It shows the correct images and tracks the target like it’s shown in the GUI demo. First, I’ve tried to calibrate using the GUI, there it always fails after the scale calibration with a warning “Failed to update the device … possibly loose usb connection” or something alike.

I installed the SDK manually, following the instruction manual for Ubuntu 18.04 LTS without errors.
