USB

The main communication channel with the controlling PC is through the ST72F651 Full
Speed USB interface, based on a Vendor Specific Class embedded in the Industrial
Communication Board firmware and a dedicated driver, part of the controlling software.
Once the USB cable is plugged to connector CON1, the Industrial Communication Board
takes its power supply from the 5V USB interface of the PC.
A second function of the USB interface is to provide the DFU (Device Firmware Upgrade)
functionality used to upgrade firmware.
The connecting cable should have a USB-B plug toward Industrial Communication Board
and a USB-A plug toward the PC as shown in
