The Egress Port uses USB. What is USB?
USB or Universal Serial Bus is the technology that features one “Universal” plug type for all USB peripheral-to-PC connections. USB replaces all the different kinds of serial and parallel port connectors with one standardized plug and port. USB simplifies the connection of peripherals to computers by providing an instant, no-hassle way to connect these USB peripherals. With USB-equipped PCs and peripherals, just plug them in and turn them on–they are automatically configured and ready for use. Just like plugging in a lamp!
