Connect, Extend, and Switch USB Signals Between Devices

Universal Serial Bus (USB), a serial interface that adds peripherals to your computer, uses physical connectors (Type A, Type B, Type C, Mini-USB, Micro-USB). A USB peripheral plugs into the port and works. No need to install a card, drivers, or software - or turn off your computer. USB configuration happens automatically.

Just plug a USB cable attached to your mouse (or, for wireless, plug a USB dongle) into a USB connector on your laptop. USB can reach 16.4 feet (5 meters), but USB extenders expand this distance up to 328 feet (100 meters) over CATx or 6.2 miles (10 kilometers) over singlemode fiber. Enlist a USB switch to add extra network ports to send signals between USB devices. Share a printer/scanner between multiple PCs.
