UsbVideoClass YUV formats don't work

Hi All.

I am developping USB Video Class device.
Our device will support YUV2 Format ans
Isochronous image stream.
I choiced Payload umcompressed format.

I tested this device by AmCap and GraphEdit.
When I clicked AmCap, AmCap said this Graph can't preview.

When I clicked GraphEdit and was connecting
Our device unit and a display rendere unit,
following error message box appeared
and I was able to connect these units.

These filters cannot agree on a connection.
Verify type compatibility of input pin and output pin.
( return code : 0x80040217 )

I found VS_PROBE_CONTROL(GET_CUR / SET_CUR)
requests by USB Analizer.
But I didn't find VS_COMMIT_CONTROL(SET_CUR).

I guess there are in inconsistency YUYV Format/Frame Descriptors or Endpoint
Descriptors.
But, I can't find.

Would you tel me documents or guides to find inconsistency ?

best regards.
