2 USB devices (eg. 2 USB CDC ACM or 1 USB ADC ACM and 1 USB Audio) simultaneously

[engleok]

I am working on the nRF52840 DK and nRF52 SDK 15.2.

I can run the USB CDC ACM example and the USB Audio example successfully.

Is there a way to create BOTH devices at the same time? Much like a USB composite device.

I tried looking at the USB HID Composite device as a reference but it seems specific to USB HID(?).

Idea is to use 1 of the USB CDC ACM device for control (send commands and receive status). And the 2nd device (whether USB CDC ACM or USB Audio to continuously receive Audio data.

thanks

Yes, that should be possible. Make sure that they use different endpoints and interface numbers.
