The Unauthorized Devices section allows the administrator to specify the unauthorized
USB devices for the Portal. Two buttons allow customization of this “black list.” The Add
new button allows a new device or device group to be added to the list and the Remove
button allows a device or device group to be removed from the list.
Selecting the Add new button allows USB unauthorization by Class or ID. If ID is
selected, then this entry unauthorizes a USB device by Vendor ID and Product ID. If
Class is selected, then this entry unauthorizes a USB device by Device Class, Sub Class
and Protocol.
Note: USB authorizations are applied in the following priority order:
1. Unauthorized Vendor ID/Product ID (highest priority)
2. Authorized Vendor ID/Product ID
3. Unauthorized Device Class/Sub Class/Protocol
