Can't find your USB hub? Why not build one on your own and have fun! This demo project puts together multiple Hexabitz H11R20 Mini USB-to-UART modules to build a customizable USB hub/switch. While not made for performance, this is not your typical USB hub. We will use lots of DMA tricks to transfer data between different USB ports, duplicate it, broadcast it and do many interesting things your normal off-the-shelf hub can't even dream about. More to come!
