ST if free to contact me about licensing the code (or improving their
own code to be USB standard compliant)..

This follows the same protocol as the lora code, so the same
server should just work.

convert to using stdio to line buffer usb output... This reduces
usb traffic like when doing hexdump...

The delay works, but could be a problem on slower systems...  It's
been reported, so hopefully a fix will happen..
