Protection of the USB READ operation:
- when restoring a controller configuration from the Local User Interface.
In that case, any file infected by a virus appears as an invalid backup file. The controller
software detects it and rejects the restore operation.
- when printing from the USB device.
Any print file infected by a virus will never compromise controller's software integrity.

Protection of the USB WRITE operation:
- during the backup of the controller configuration, from the Local User Interface.
The backup is performed by the internal controller software. It cannot contaminate the USB
device by any threat.
- when making a Scan To File to the USB device:
The Scan To File operation to USB device is performed by the internal controller software. It
cannot contaminate the USB device by any threat.
