Disable USB Mass Storage IT policy rule

Description

This rule specifies whether USB mass storage and the media transport protocol are turned on. The media transport protocol permits a BlackBerry device user to transfer media files from a computer or BlackBerry Desktop Manager to a BlackBerry device or media card. When you transfer files using the media transport protocol, the device does not protect the files using content protection and does not encrypt the data on the media card, even if you configure the External File System Encryption Level IT policy rule.

This feature is not available for BlackBerry Desktop Manager 4.2.2 because the Roxio Media Manager uses the media transport protocol to transfer files.

For more information about protecting data that a device stores on a media card, see the BlackBerry Enterprise Solution Security Technical Overview.
