The USB connection on the printer user interface

Introduction
A USB connection is available on the touch panel.
This USB connection is used to:
• Install / upgrade the controller software
• Backup and restore the controller configuration
• Collect log files into a USB device ('Get logfiles to USB stick' button in the 'Launcher'
application)
Security on the USB port
General USB port protection:
• Booting from the USB device is not possible.
• Executing any programme present on the USB device is not possible
The Autorun is disabled and no operation on the controller can execute a programme on the
USB device.
• Propagating on network any infected file present on the USB device plugged on the USB port
is not possible
Read from / write to USB device protection
• 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.
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.
- during the storage of the log files
The backup is performed by the internal controller software. It cannot contaminate the USB
device by any threat.
