I got my webcam which is the Logitech C270 when trying to set up the "video capture device", it either is detected but when pressing "ok" leaving everything to default the video doesn't appear on the preview or the device sometimes is not detected at all.
Here is the log : https://gist.github.com/6a4a16ac695e6440b25b6823d9d5d497
