I would like to use the USB dongle with the Openthread CLI example (and eventually an open thread app) as the SDK is just too big and overpowered for my prototypes, I would like to use the USB CDC as the Shell to communicate with the CLI and zephyr.
https://github.com/zephyrproject-rtos/zephyr/issues/16761
I also looked at the Thingy applications/connectivity bridge which is similar
I can program using nrfconnect or nrfutil, but I never see the USB CDC serial port come up after programming.
I'm using nrfconnect sdk 1.4.0 os OS X
I have added to boards
nrf52840dongle_nrf52840.overlay

&uart0 {
status = "okay";
};
/ {
/*
* In some default configurations within the nRF Connect SDK,
* e.g. on nRF52840, the chosen zephyr,entropy node is &cryptocell.
* This devicetree overlay ensures that default is overridden wherever it
* is set, as this application uses the RNG node for entropy exclusively.
*/
chosen {
zephyr,entropy = &rng;
};
};
Also added a config overlay, I tried with and without some UART interrupt setting mentioned in other posts.

I also added the dongle to Allow to sample.yaml
