EZKIT 561 using h.264 BP encoder.  I am seeing LED14 flash.

It indicates that the USBIO is upset.

I checked and it is throwing an exception here in adi_usb_net2272.c:


    ADI_DCB_CALLBACK_FN epZeroCallback =  pDev->PhysicalEndpointObjects[EP0].pLogicalEndpointObj->EPInfo.EpCallback;


    ucStatus = _inpb_d(USBCTL1_ADDR);


        /* ensure that endpoint 0 has a callback installed */
    if (epZeroCallback == NULL)
        return -1;
    if(intStatus & ROOT_PORT_RESET_INT)
=====>        epZeroCallback(pDev->DeviceHandle,ADI_USB_EVENT_ROOT_PORT_RESET,0);


The MP encoder works.  but not the BP.  When the code above is hit, the EZ USB is not recognized on the PC.

Has anyone seen this before?
