The Universal Serial Bus (USB) is one of the most widespread technical innovations in personal computer and home consumer applications over the past few years. Keyboards, mouse devices, printers, webcams, and several other computer peripherals are available with this type of connection. This success is due to some bus characteristics, such as simplicity, plug & play features, hot plug support, and, particularly, the possibility of supplying power to the devices. USB offers good noise immunity due to its differential type signal transmission.
