I am trying to use imaqtool with a Motionblitz EoSens mini2 camera, on Widows 10, with the gige adaptor.
The device is recognised by imaqtool, but when I want to have a preview it only displays a white image with a red X.
I tried the three recomendations given on that page: but it does nothing.
Would anybody have hints for me?
Many thanks!

I don't have your camera but I had a similar issue with the red cross of death.
I had camera refresh problem with my NVIDEA gpu conflicting with opengl so needed to use the opengl software driver.
After using the statement opengl('save','software') to default to the software driver on matlab boot, I lost all camera feeds and like you had the red cross of death.
After reseting this feature so that matlab always booted with hardware acceleration opengl('save','none') and restarting matab all video returned.
I now use the statement opengl software in my scripts to fix the camera refresh problem.
Hope this helps your problem, but likely there is some low level graphics compatability issue with your camera
