    UAC "This device cannot start. (Code 10)" error in Composite device.



      I am trying to build an USB composite device (UVC + UAC + CDC). Among these, the UVC and CDC works. But the UAC is shown in Windows Device Manager with "This device cannot start. (Code 10)" error. I used Thesycon Descriptor dumper utility to inspect the descriptors. It reports error for the UAC Endpoint descriptor. I m confused with this.


      I am using USB HighSpeed.  Firmware is attached.
