Having problems updating iConnectMIDI4+'s firmware

When attempting to update the firmware with the iConfig application, the status declares that it’s rebooting to boot-loader mode, then a pop-up notifies of a communication error, and nothing happens. No firmware update actually takes place.

For successful firmware upgrades on the iConnectMIDI4+, the computer performing the upgrade (via iConfig) has to be connected to the 3rd USB Device Jack on the rear of the device.
