On the Device Control settings page, a list of various device types and their respective device access permissions are provided.
Once a particular permission is set to a device type, a device connected to the system and categorized under the respective device type will behave according to the set permission.
For example, if "Block" permission is set to "Wireless > Bluetooth" in Device Control, internal Bluetooth ( Built-in Bluetooth of laptop computers) as well s external Bluetooth (External Bluetooth Dongles) will get blocked and hence not be accessible to the user.
