USB deive CDC ACM

[Srikara]

My device and Software details are as below

nRF52840 DK

nRF connect SDK 2.0.2

Want to verify USB device role for nRF52840 DK.

Found the below example and its documentation 

samples/subsys/usb/cdc_acm

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.2/zephyr/samples/subsys/usb/cdc_acm/README.html

The main doubt here is the documentation says "this project requires an USB device driver, which is available for multiple boards supported in Zephyr."

So to test this how i can include driver also in the project before building and flashing the final binary to the nRF52840 board.

Can anyone help with complete steps

Hi,

The driver will be included automatically by the build system if you build the sample for a board that has a valid USB device driver available, for instance the nrf52840dk_nrf52840 target. 

Best regards,
Jørgen

Thanks for the information. When I connected the board it is connected as COM6 and when I type the data i can see the data. For e.x: if I type letter 'a' i can see letter a. I think this is the expected behavior.

one more thing is one USB port is used as power and other USB is enumerated as com port which is com6 here. When I am using JLINK(RTT) for debugging i am using with USB, in future project this USB power lines will be used for power but from external source instead of laptop. That time how can I debug.
