Nordic 52840 usbd MSc and CDC can be used together. how to assign?

Hi,

Yes, they can be used together. Such as device is called a USB Composite Device(a device that supports more than one device class). To get this working, I suggest starting with the USB MSC Example, and then add the relevant code for the CDC ACM USB class to that example.(i.e. you need to “merge” the 2 examples).

Please go through the "step 3" on how to install the driver here, under "Testing".
