Hello
In our tests the StarGo software works fine with Win11 and we didn’t find yet connection issues.
When the operative system cannot connect to the StarGo through the USB port, before to roll back to the previous operative system version, in order to restore the correct functionality, is suggested to perform a full system restart, switching off the power from the StarGo board and restarting the PC as well.
In case after the restart, the connection has not yet been restored, phisically unplug the USB cable and plug in again, better if in a different USB port.
Best regards
Stefano
