USB3 vision XML in camera for NI vision builder

[ZRuler]

I am design a camera compatible with USB3 vision standard. After the camera connects PC by USB3.0 cable to PC, I use NI Vision builder to open the camera. The XML is found transfered correctly from camera to NI vision, and ROI, PixelFormat, PayloadSize are all read and displayed in NI vision application window. However, I don't know
how to update my xml to activate the button "Grab" of NI Vision builder. I don't know the NI vision builder requirement  to the xml, so that I can't have the grab button activated to start picture capture.

In one word, how to make the xml to adapt the NI vision to start picture grabbing?

The only requirements NI IMAQdx has with regards to USB3 Vision compatibility is that the camera complies with the USB3 Vision specification, which has requirements for the XML file to be Genicam-compliant.

The USB3 Vision standard has a set of compliance tests that are used as part of certification against the standard. Have you tried running those against your camera?
