vidGrabber don't recognize the RGB format of camera and defaults to YUY2

Hello,
I’m using a Kurokesu C1 camera in Windows 10.
It has a steady 30fps rate which I successfully tested with Amcap capturing in MJPEG/RGB 1280x720. vidGrabber seems not to be able to find the right RGB format and switches to YUY2, or at least that’s what I get in the log:

[notice ] —
[notice ] 0: Kurokesu C1
[notice ] ofDirectShowGrabber: initGrabber(): choosing 0
SETUP: Setting up device 0
SETUP: Kurokesu C1

SETUP: trying format RGB565 @ 1280 by 720
SETUP: trying format YUY2 @ 1280 by 720
SETUP: Capture callback set
SETUP: Device is setup and ready to capture.

This way I get a very low frame rate, maybe 10fps.
YUY2 mode is slow, as also stated in camera specifications.
Anyone knows how to make it work in RGB at full frame rate?
Thank you very much in advance.
