Designer Gonglue Jiang presented an interesting concept, which is called «Infinite USB Plug».
His idea seems very useful, because now not necessarily have a lot of USB-connector, but enough to have just one. So, now need to purchase USB-hubs no longer required, and the lack of ports, too, will go into the past. A designer also suggested tagging plugs colored stripes, so as not to be confused in fact any device owned by one or another cable.
However, small defects in the development there is still is a need to disconnect from the port all connected devices in the event that we need to pull the plug from the first of them. Well, more questions may arise with the supply sufficient for several devices of power to the port USB.
