If you encounter problems during a firmware update at the step where you have to select a port – make sure you have a proper USB cable connected. Having indicators blinking on expansion board doesn’t necessary confirm that all is good. In fact, you have to hear a windows recognition sound at the moment of plugging in. The update (port recognition) became possible for me only after I tried three different USB cables. Cheers! 22 May, 2017 at 11:29 #198 Anonymous If you don’t want to apply the script to the wrong USB port, you can check which one corresponds to your device from the “Device Manager”. Open “Control Panel” > “Device Manager” > “Ports”. Then by plugging/unplugging your device, you will see which “COM” port activates/deactivates.
