/** Endpoint 0 task for USB Audio devices
 *
 *  Function implementing Endpoint 0 for enumeration, control and configuration
 *  of USB audio devices. It uses the descriptors defined in ``xua_ep0_descriptors.h``.
 *
 *  \param c_ep0_out    Chanend connected to the XUD_Main() out endpoint array
 *  \param c_ep0_in     Chanend connected to the XUD_Main() in endpoint array
 *  \param c_aud_ctl    Chanend connected to the decouple thread for control
 *                      audio (sample rate changes etc.). Note when nulled, the
 *                      audio device only supports single sample rate/format and
 *                      DFU is not supported either since this channel is used
 *                      to carry messages about format, rate and DFU state
 *  \param c_mix_ctl    Optional chanend to be connected to the mixer core(s) if
 *                      present
 *  \param c_clk_ctl    Optional chanend to be connected to the clockgen core if
 *                      present
 *  \param dfuInterface Interface to DFU task (this task must be run on a tile
 *                      connected to boot flash.
