Device Control USB not getting blocked

ITSM W/ Member Posts: 16 Junior Protector


I'm trying to block USB storage devices, like USB and Smartphones but it's not working.

Can you tell me how to block these devices, so that employees can't use their personal USBs and Smartphones to store their personal data on the work computers?

    Hi ITSM


    You may need to block it using Hardware ID class. Some USB devices have different classes.


    You can limit or block access permissions for removable drives using Device control. Refer to the following link for instructions:

    Note: Device control can only be configured from the Policy Manger or PSB Portal (Profile editor). There is no local configuration user interface.

    Hi ITSM,


    To block/disable mobile phone storage access via USB cable in Policy Manager 14.x using Device control, you need to block the following device classes.


    Add a device access rule as below:


    Display name: Mobile Phone storage
    HardwareID: USB\Class_FF
    Access level: Blocked


    Repeat this rule with the below mentioned device classes to block all smart phones:


    HardwareID: USB\Class_00
    HardwareID: USB\Class_08
    HardwareID: USB\Class_02
    HardwareID: USB\Class_EF

    Can you tell me please does these classes include wireless keyboard and mouses and barcode scanners, because most of the PCs I manage with Policy Manager have Barcode Scanners and wireless keyboard and mouses.

    Thanks in advance.
