High Quality Content by WIKIPEDIA articles! A USB decoration is a device that uses the Universal Serial Bus (USB) connector and sometimes the protocol on a computer or other host, and is primarily a decorative device (using the USB port for power). Decorative computer peripherals have been around for a long time, in the days of front panels, programmers would sometimes use them for decorative light displays. USB decorations are the most prominently used today, the popularity of USB letting them work on most modern computers. Most USB decorations do not use the communications features of the USB bus or comply with USB standard power discipline. This can interfere with the purposes for which USB was designed, especially if the device is drawing the full 500mA of power available. The usual power consumption is only 100mA, which will not impact the computer's PSU if suddenly connected, without it identifying itself first.
