Arduino WiFi Shield upgrade
=========================================
Instructions:
To access to the USB devices correctly, the dfu-programmer needs to have the root permissions.
You can upgrade the firmware of the antenna togheter with the shield firmware or only the shield firmware
if there aren't changes on the antenna firmware.
Use the '-h' parameter for help
