Speculation mode engaged. For one thing, if a USB Hub functionality was also built in, you then only need one physical USB connection between radio and computer, and you could have full Rig Control, + USB Audio I/O, a well as the usual KX3 utility functionality (firmware updates etc.)
Ideally, a galvanically isolated USB link to/from the outside world, preventing ground loops. Such devices are available, such as (but not only) :- https://www.analog.com/en/products/ltm2884.html (Not the smallest of implementations, just referenced as an example of available functionality, available now.) No noisy micro SMPS needed either, as the rig already has it's own internal power for the internal side, and the PC would power (via the cable) the "external" side. From what I recall of the KX3 schematic, the Audio codec chip has plenty of unused spare audio I/O lines, so at the very least, analogue Audio I/O could (in principle) be possible with minimal changes to the physical design (but not firmware I suspect.) Easy for me to say that, I don't have to do it. But that alone would make an excellent rig even better. 73. Dave G0WBX.
