USB decoration : ウィキペディア英語版 | USB decoration
A USB decoration is a decorative device that uses the Universal Serial Bus (USB) connector for electrical power, and sometimes the protocol, on a computer or other host. In addition, some lightweight devices (e.g., a small lamp on a gooseneck stalk) use the USB connector itself for mechanical support. ==History== Decorative computer peripherals have been around for a long time; in the days of CPU front panels, computer hackers would sometimes use them for entertaining or amusing "Blinkenlights" displays. Today, USB-powered decorations are the most prominently seen examples, since the popularity of USB lets them operate on most modern computers. The USB standard can also be used to power devices via AC adapters traditionally used for mobile devices, allowing manufacturers of these decorations worldwide compatibility without the need for any power converters for different socket form factors.
