Patience and looking around pays
Downloaded first the driver from the code laboratories page (3 $, affordable).
In my vs 2017 project I switched from my python 3.6 64 bit to the 3.6 32 bit environment. If you never did that, microsoft has a nice tutorial how to have multiple python environments in parallel and how to bind your code to the one that works best for you.
Now my code started to work with the ps3 eye cam
cap = cv2.VideoCapture(0)
ret, img = cap.read()
if ret:
cv2.imshow("image", img)
cv2.waitKey(0)
