Hi,
This post is just to share with all of you (who would need it) a simple application interface (attached here) that uses the nRF52840 USB since we spent some painful period of time to understand it and make it work (now it perfectly works).
This attached zip file contains a verbosely commented C file that initially started from the Nordic example nRF5_SDK/nRF5_SDK_v17.0.2/examples/peripheral/usbd_cdc_acm/main.c. For sure it may be not perfect and more complex implementations could be done from this straightforward one.
Our use case was the SDK 17.0.2 and the nRF52840 (SoC revision 2).
Hope this may help others.
Best regards,
Thierry
