The USB Dongle - Software Protection Device driver is related to a hardware dongle that is often used as a form of software copy protection or license verification. These dongles are physical devices that plug into a USB port on your computer, and they typically contain an encryption key or a license that grants access to specific software. The software checks for the dongle to ensure that the user is authorized to run the application.

These types of dongles are often used in industries where software piracy is a concern, or for specialized software that requires protection against unauthorized use. Examples include engineering tools, CAD software, or specialized applications for creative professionals (like design or audio software).
