CYCX3_UVC is not working with MS Media Foundation in Windows 7
CYCX3_UVC is a sample firmware in EZ-USB FX3 SDK v1.3 and it is working fine with (DirectShow + Windows 7) or (MMF + Windwos 8).
But it's not working in (MMF + Windows 7 usbvideo.sys) environment.
When I try to launch MFCaptureD3D, for example, which comes from MS Windows SDK v7.1, it just gives error code: 80070491.
I tested with other Webcams but they are all OK.
So, I think it's kind of firmware or driver problem.
Is there any way to solve this problem?
