Hi Guennadi, The cameras in question are USB-3.0 industrial cameras from The Imaging Source. The ones I tested were the DFK UX250 and DFK UX264 models. I do not know if there are other devices that have the AUTO_UPDATE flag for various properties.
Since I received no immediate answer I tried fixing it myself. The result can be found here: https://patchwork.linuxtv.org/patch/43289/ Cheers, Edgar
