I like the idea of utilizing the USB more, but most (non Dynon) devices I want to connect are serial. Perhaps Dynon could use USB for it's devices (SV-GPS-250, SV[ch8208]XPNDR[ch8208]26X, SV-COMM-33X, SV-TEL-33X, SV-KEYBOARD-40X, etc) to free up the serial ports. It's a simpler connection then the nine wire network connection although I like the way the network works - almost like USB but with a lot of redundancy in the wiring. I wonder if there is a TSO'd USB port replicator or can we use an off the shelf unit :-?.
