Are there any drivers available for the Logitech C910 after OS 10.6.x? It works in Logitech Webcam Software, but the camera isn't recognized in any other application that accesses the camera. A [similar question from 2014](https://apple.stackexchange.com/questions/144974/hd-video-capture-software-for-logitech-web-cam) led me to trying the webcam out in QuickTime; in my case, QuickTime recognizes the C910's microphone as "Unknown USB Audio Device," but doesn't recognize the camera.

I've looked both in the Logitech support site and elsewhere for possible drivers, and haven't found anything, so I'm aware that there may be no solution for this. 

Update: restarting the computer did help a late 2015 trash can Mac Pro recognize the camera, but restarting did not work for a late 2011 MBP. Meanwhile, it worked perfectly on a late 2012 MBP without much struggle. All these are running El Capitan.
