UVC Endpoint companion descriptors

I am working to create firmware for USB Video class, and I am using the USB VideoClassBulk and the HD example to send uncompressed data.  So far, I seem to be succesful in transmitting test patterns (using the DMA as the source), but when I use USB Device Viewer (from Visual Studio) to view the USB descriptors, I see some errors related to the Endpoint compansion descriptor.  Here is the suspect code:

    /* Video control status interrupt endpoint descriptor */
    0x07,                                                             /* Descriptor size */
    CY_U3P_USB_ENDPNT_DESCR,        /* Endpoint descriptor type */
    CY_FX_EP_CONTROL_STATUS,           /* Endpoint address and description */
    CY_U3P_USB_EP_INTR,                        /* Interrupt end point type */
    0x00,0x04,                                                   /* Max packet size = 1024 bytes */
    0x01,                                                            /* Servicing interval */

    /* Super speed endpoint companion descriptor */
    0x06,                                                            /* Descriptor size */
    CY_U3P_SS_EP_COMPN_DESCR,    /* SS endpoint companion descriptor type */
    0x00,                                                            /* Max no. of packets in a Burst : 1 */
    0x00,                                                            /* Mult.: Max number of packets : 1 */
    0x00,0x04,                                                  /* Bytes per interval : 1024 */

This is what USB Device Viewer shows:

          ===>Endpoint Descriptor<===
bLength:                                  0x07
bDescriptorType:                   0x05
bEndpointAddress:               0x82  -> Direction: IN - EndpointID: 2
bmAttributes:                          0x03  -> Interrupt Transfer Type, Usage Type = Periodic

*!*ERROR:     Endpoint Companion Descriptor missing
wMaxPacketSize:                  0x0400
bInterval:                                 0x01
*!*CAUTION:  Unknown bDescriptorSubtype
          ===>Descriptor Hex Dump<===
bLength:                                  0x06
bDescriptorType:                   0x30
06 30 00 00 00 04

Any thoughts for why this is happening?  I tried this with the supplied code, and I see the same error. 

As I said, I am still getting video, so this is not a fatal error, but I get concerned when I see these things.  Any ideas?

Thanks
