Infinite USB
But now there is someone (Gonglue Jiang) who solved the problem of having to much USB devices and not enough ports.
Well the pictures speak for themselves. Just keep adding devices.
It is just a concept, but I hope it will hit production very soon. I am wondering though how much devices can be put on the stack before something starts to smoke or beg for power.
