Actually... My K3 does exactly that... one USB cable that everything
flows over.... digital/CAT and Audio. I do have the schematics for
that board so I can see how it's done from a hardware standpoint...
*** Do does my FTDX10. Well, at least it used to. It has a USB hub chip,
a USB audio chip, and a USB serial-port chip. The serial port functionality
died. I replaced the chip, but it's still dead.
I just found a USB stack that can work on a raspberry pi pico. "TinyUSB". I'm tempted
to play with that to learn. The RPI pico has hardware debug! That stack
also works on many other processors, including the Teensy's. Or maybe an RPI zero?
RPI zero has an HDMI port.... and I'm pretty sure it supports I2C.
