combining USB HID (USBD) and USB Audio (USBD_Audio) Possible?

Hi,

It's possible, but we don't have any examples that combines them. Maybe looking at the usbd_hid_composite example might give you some clues on how to do it.

Hi Sigurd,

I tried to combine but  got struck in USBD initialization .

USBD example initialize USBD as :

ret = nrf_drv_usbd_init(usbd_event_handler); 

USBD_AUDIO initialize USBD as:

 ret = app_usbd_init(&usbd_config);

I cant  use these two initialization as it enters to infinite error loop.

how to use these two functions together?
