This validation procedure is performed on both the MDM Administration Console and the LG Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow USB" setting in the MDM console. 2. Verify the setting is disabled. On the LG Android device: 1. Unlock the device 2. Connect device to test PC using USB cable. 3. Navigate to the PC connection: Open device Notification bar >> select USB connected. 4. Verify all USB connection types, except for "Charge only", are disabled and cannot be enabled. Since the USB storage and USB media player cannot be used, the USB function is only available for device charging. If the "Allow USB" setting is enabled or if the user is able to enable the setting on the device, this is a finding.

Fix text

Configure the mobile device to disable data transfer capabilities through USB. On the MDM Administration Console, disable "Allow USB".
