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 activating the auto-gain property. These property changes are not queried by the UVC driver, unless it already has the property marked as auto update via UVC_CTRL_FLAG_AUTO_UPDATE. >From what I have seen, it seems that this flag is not checked when indexing the camera controls. However it is checked when using extension units, so all properties loaded through such a unit are being updates as one would hope. My questions: Is it intended that properties cannot mark themselves as autoupdate? If yes: Is there a recommended way of working around this? Do all autoupdate properties have to be in an extension unit? If no: What should a fix look like? Regards, Edgar
