History 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. USB Interface Main article: Universal Serial Bus 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. Often, several decorations are connected to a single USB hub which, if it has no external power connection, is limited to 400mA. With each device drawing 100mA, it is therefore only possible to run four low-power decorations. A USB hub without external power cannot run a high-power decoration. Decorative usage USB decorations may have no useful functionality other than aesthetic ornamentation. For example, lights, lighted cables, displays, miniature disco balls, aquariums,, terrariums, waterfalls and pole dancers that connect to a USB port are all USB decorations. There are many USB-based decorations in existing productseyboards with impractical backlighting (such as ones that only turn on while pressing a key, and ones that flash to the beat of a song), mice that (when the computer is turned off) turn on/off their light to a pre-programmed beat, or printers that show random quotes on LCD screens when not in use. A similar concept exists in the form of decorations that are powered by car adapter plugs. Functional semi-decorations A sushi-themed USB Flash Drive It is not uncommon for a USB decoration to have a non-passive and practical purpose. Nightlights, typing speedometers, a beverage chiller,, fans and nodding dogs that guard internet connections are all examples of USB semi-decorations. Flash drives may similarly be themed for aesthetic value. Although these are not pure USB decorations, they are still decorative. Usually these types of devices are simpler; all of the power can be used for the main function, not for the decoration.
