USB_HOST_AUDIO_V1_0_STREAM_RESULT_REQUEST_STALLED	Request was stalled
USB_HOST_AUDIO_V1_0_STREAM_RESULT_HANDLE_INVALID	The specified Stream Handle is not valid
USB_HOST_AUDIO_V1_0_STREAM_RESULT_END_OF_DEVICE_LIST	The end of the device list was reached.
USB_HOST_AUDIO_V1_0_STREAM_RESULT_INTERFACE_UNKNOWN	The specified interface is not available
USB_HOST_AUDIO_V1_0_STREAM_RESULT_PARAMETER_INVALID	A NULL parameter was passed to the function
USB_HOST_AUDIO_V1_0_STREAM_RESULT_CONFIGURATION_UNKNOWN	The specified configuration does not exist on this device.
USB_HOST_AUDIO_V1_0_STREAM_RESULT_BUS_NOT_ENABLED	A bus operation was requested but the bus was not operated
USB_HOST_AUDIO_V1_0_STREAM_RESULT_BUS_UNKNOWN	The specified bus does not exist in the system
USB_HOST_AUDIO_V1_0_STREAM_RESULT_UNKNOWN	The specified audio stream does not exist in the system
USB_HOST_AUDIO_V1_0_STREAM_RESULT_FAILURE	An unknown failure has occurred
USB_HOST_AUDIO_V1_0_STREAM_RESULT_FALSE = 0	Indicates a false condition
USB_HOST_AUDIO_V1_0_STREAM_RESULT_TRUE = 1	Indicate a true condition
