The camera device is detected just fine, it seems:

Same here (Dell XPS 15 L502x). Cheese's preferences window shows that it has detected the camera device, but nothing works and there are no error messages in the terminal.

Video capture works fine in vlc.

Hi all the same problem, I made a fresh install on a Dell xps-l502x:
Dont works with VLC, Cheese and GTK UVC

Hope you guys can help me with this problem.

@andres: on my L502x laptop, guvcview does recognise the camera - the output shows something like this:

Whether it works definitely is kernel-dependent, though. It works just with 3.15.7 (there are a couple of 'resource temporarily unavailable messages at the start, then it works), but 3.16-rc7 keeps compaining about the device being unavailable or the buffer being empty and I just get a black screen, even though the white LED comes on to show the camera is being used. The stock 3.13 kernel works for me (at least it did when I tried it in a VirtualBox VM: it missed a lot of frames but did display a picture). Even thought guvcview doesn't work with kernel 3.16, motion and Skype both do. Odd.

Cheese still doesn't work with any kernel, which is disappointing.

@Rocko As you say In my case it seem to be a kernell problem, what do you recomend me ?

Attached the lsusb and kernel information, the webcam stills down. (:/)

So is there any advance on this issue?

I'm still having this problem on 14.04.

Both cheese and skype show black screens but I it you go to a site like http://www.testmycam.net/ the camera works as expected.

???

Can I provide any further data for analysis?
