This is just a minimal PoC for an "interesting" idea.

I just changed USB_CFG_VENDOR_ID and USB_CFG_DEVICE_ID in the usbconfig.h file to emulate an ICOM-7300.

Sniff traffic generated by WSJT-X:

socat /dev/ic7300,raw,echo=0 \
  SYSTEM:'tee in.txt | socat - "PTY,link=/tmp/ic7300,raw,echo=0,waitslave" | tee out.txt'

hexdump in.txt

This technique works! :)
