Disable USB Mass Storage IT policy rule


This rule specifies whether USB mass storage and the media transport protocol is turned on.

Default values

The default value in the Advanced security and Advanced Security with No 3rd Party Applications IT policies is Yes.

The default value in all other preconfigured IT policies is No.


The media transport protocol allows a user to transfer media files to the BlackBerry® device from a media card. If you change this rule to Yes, a BlackBerry device cannot access a media card that is connected to the USB port. This means that the ability to transfer files to a media card using the Roxio® Media Manager with the BlackBerry® Desktop Manager versions 4.2.2 and 4.3 is turned off.

Minimum requirements

  • Java® based BlackBerry device
  • BlackBerry® Device Software version 4.2
  • BlackBerry® Enterprise Server version 4.0 SP6
