    • You can find the ID of any connected devices at ‘Security Sub-systems’ > ‘Device Control’ > ‘Hardware Path’ column.
    • You can use a wildcard character '*' if you want to cover a range of devices with similar IDs. For example, to include all USB storage devices whose IDs start with “4C5310”, you could enter:
