A High-Speed USB Bridge Cable is a special USB cable designed to connect two computers and allow them to transfer data directly between each other. It's essentially a type of USB data transfer cable used for migrating files, transferring data, or sharing resources between two PCs without the need for a network. The cable typically comes with built-in electronics that facilitate the communication between the computers, and a driver is needed to ensure that the operating system recognizes the cable and the data can be transferred.
