use NrfConnect SDK with 52840 dongle USB CDC Shell/console

This did work nicely until SDK 1.5.1. With SDK 1.6.0 and 1.6.1 the USB shell does not respond anymore. Any idea what has changed with SDK 1.6.0?

Actually I had that in my main.c, but also had a bunch of other stuff from the subways/usb/console that may have been breaking bits using it as a console.

So I added to prj.conf ( I may see if the CONFIG_USB_UART_CONSOLE is needed, but hey this works...)

CONFIG_GPIO=y
CONFIG_USB=y
CONFIG_USB_DEVICE_STACK=y
CONFIG_USB_DEVICE_MANUFACTURER="SER Consulting LLC"
CONFIG_USB_DEVICE_PRODUCT="BaseBoard Thermostat"
CONFIG_USB_DEVICE_VID=0x1915
CONFIG_USB_DEVICE_PID=0x520F
CONFIG_USB_CDC_ACM=y
CONFIG_USB_UART_CONSOLE=y

CONFIG_UART_SHELL_ON_DEV_NAME="CDC_ACM_0"

I created a nrf52840dongle_nrf52840.overlay that is just a duplicate of the dk version

It just needed the include and usb_enable in main.c to work. I think the extra code tried to use it as a console instead of a shell... So I may be trying to create a multi device with 2 CDC's on it, one for shell and one for console, but I'll experiment with this first. May want to add this in to the SDK as an overlay for the dongle.

I was literally trying the same thing today! In addition to the changes to the config that you already added you also need to enable the USB subsystem in samples/openthread/cli/src/main.c by adding a call to usb_enable. With that change I got the OpenThread CLI working on the PCA10059:

Tried just about everything I can think of. As an alternative, can I get the console/shell over bluetooth UART? I was looking at the shell_bt_nus and chi_lpuart (what does chi stand for?)

The console by itself worked and printed to the USB and I had a usb device to connect to. I pulled a clean 1.4.0 dev environment. then copied the modifications to Kconfig, prj.conf, CMakeLists.txt (Hmm, do I need do do a zephyr update or something for the Cmake? and main.c. I don't get a usb device to connect to. Since the console did not have a board overlay file, I did not create one for the USB dongle. I will also try that.

Quite well hidden, but that does seem to work for the console. I will try using those parameters (and the code in main.c). One possible issue is that it seems there is a difference between the zephyr console and shell, and the CLI example needs the shell. But I also have the dual cdc_acm_composite example, and may be able to use that to figure out how to get both console and shell off of the USB port

Could you try to get the sample zephyr\samples\subsys\usb\console\src\main.c to work with the 52840 Dongle? If you do, then you can port it to the openthread sample. I was able to use that sample to log via USB on the nRF52840 DK at least.
