Actually... My K3 does exactly that... one USB cable that everything

that board so I can see how it's done from a hardware standpoint...

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.

Or we could use one of the traditional serial ports built into the Teensy hardware.
There are eight of them. But looking at the Main Board schematic, I don't see much in the way of unused pins.

device. There appear to be Arduino libraries for all of these
devices.

That’s a good idea and actually, I think I saw an article on someone
using a USB server device with their T41. I don’t know how that works
but its out there…

Jerry: could you just use the standard Serial + Audio USB
configuration on the primary microUSB port, then add an external
USB-to-serial adapter plugged into the USBhost port & use that
additional interface for your CAT control ?? Just a thought...

All,

I have been working on CAT ( remote control ) for the T41. I
re-architected it to a data-driven approach that is much cleaner and

will be easier to maintain and expand.

I have the basics running: read & set the frequency, read & set the
volume and mike gain, set the operation mode, make it transmit. It
is an emulation of the Kenwood TS-2000. There is a LOT of stuff that
we don't do yet.

I have given the code to Jack. I hope it winds up in the permanent
archive.

Right now, I am getting nowhere fast with the next step: piping
audio over the USB. With that, we would be able to run digital modes
with

nothing but a USB cable between the radio and a PC.

USB function is selected by the "USB Type" pulldown at the Arduino

IDE. There are various combinations of functions, but not the one
that we need: two serial ports, plus audio. One serial port for the
teensy uploads & Serial printf()s, a second serial port for CAT
control, and an audio port.

The code that implements these USB functionalities is buried in the
Teensy "core" - the actual TeensyDuino code. In my system this is
at:

c/Users/Jerry/AppData/Local/Arduino15/packages/teensy/hardware/avr/1.59.0/cores/teensy4.

The definitions of the USB choices are in usb_desc.h. It's basically
a big array of #define's. Lots of sets of #defines, each set in an
#elif section.

ANYWAY, I hijacked the "USB_TRIPLE_AUDIO" section and replaced the
third serial port with audio.

Big fail. It compiles and loads, but then the "composite USB device"
does not start, there not only no audio, there are no serial ports.

Without serial ports, I have to hit the button on the Teensy to
upload new code to it. I'm at a bit of a loss as to how to
troubleshoot it.
USB is pretty complicated...and no debugger. Can't even do debug
printf's. One possibility would be to hook up a not-USB serial
interface to a couple of teensy pins. Or do what I did once upon a
time...find an unused I/O pin and have it emit morse code.

The Teensy is limited to 8 USB "Endpoints". That limits the number
of USB devices you can have active. Two serial ports plus audio
maxes it out. Which is too bad. There's also a simulated disk
drive, which could come in handy.

Any USB experts out there?
