Hello. I am experiencing the exact same problem with the same videocam after purchasing a new Windows 10 PC. The C920 worked fine with my Windows 7 PC but this fresh install on a new Windows 10 unit is not working.
Michael, Adam at US tech support is helping me. Perhaps you can fill him in? I know you have mentioned here that the next update should fix it, and that the update has been delayed. I assume you mean an update to VST Connect itself, not Cubase.
Dr, do you have the link to that old version of a logitech web camera utility from 2012 ? If so, can you please share it?
