Webcam detected but malfunctioning, works on Ubuntu and Windows

On Arch, there are two ways my webcam fails which are independent of the used application (e.g. cheese, guvcview):

1) I get one frozen picture of graphical artifacts. No stream.

2) I get a low frames-per-second, distorted, low-quality stream.

The webcam LED is on in both cases and goes off after exiting the application.

It's the integrated webcam of a Dell Latitude E6530.

lsusb calls it: Microdia Integrated Webcam

lshw calls it: Laptop_Integrated_Webcam_E4HD

Driver: uvcvideo

Tried linux 3.14.19-1-lts and 3.16.4-1. There's no suspend/resume involved.

Running Ubuntu 14.04.1 LTS or Windows 7, the webcam works flawlessly out-of-the-box.

As I'm not seeing any error messages, the device is detected and kind of working, any help on how to find the cause would be great.

Here: see the "Note" at bottom of section and try adding that code to uvcvideo.conf:

Didn't fix it. I'm seeing exactly the same behavior. Thanks anyways!
