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 fix

Hi all,
I have some USB-3.0 cameras that use UVC.
These cameras offer auto updates for various properties.
An example of such a property would be gain, that will be adjusted when

As mentioned in my last mail, I took the freedom and uploaded the lsusb

bayer 16-bit patterns. You can find them here:
