Webcam Issues - Black screen in Cheese and guvcview

[InsertNameHere345]

Hello,

I am currently in the preparation stages for my final year project at university and need a working webcam for an OpenCV application. I am running 14.04. However, when I open Cheese, all I find is a black screen. I have tried to receive video using guvcview also, but to no avail. The following is the output from dmesg after plugging the camera into a USB slot on the front of my system (you can see that I have done this several times):

[ 2128.933628] usb 1-1.1: USB disconnect, device number 5[ 2133.230578] usb 1-1.1: new high-speed USB device number 6 using ehci-pci

It appears to recognise the camera, however the information displayed using lsusb appears somewhat vague:

Is there anything that can be done to fix this issue? One of the requirements for the project was to use a CCD webcam which are awkward to find cheaply. However, some of the specs can be found on the retailer's site: http://www.aliexpress.com/snapshot/6316843123.html

Thank you for your help.

I have also ran guvcview in the terminal, which gave the following ouput. It appears that frames are not being grabbed for whatever reason:

Same here. ubuntu 64bit 14.04 Microsoft (har-har) LifeCam Studio

cheese works, overlaying is on ffmpeg stream with video4linux2 works, outputing it with vlc, skype, teamviewer, google hangouts chats all work.

but all of these ever recieve is some low framerate 640x480 image:

t@tsu:~$ luvcview
luvcview 0.2.6

SDL information:
  Video driver: x11
  A window manager is available
Device information:
  Device path:  /dev/video0
Stream settings:
  Frame format: MJPG
  Frame size:   640x480
  Frame rate:   30 fps

video4linux control pannel works (albeit two errors on start)

Unable to get menu item for Exposure, Auto, index=0

 Will use Unknown

Unable to get menu item for Exposure, Auto, index=2

 Will use Unknown

and indeed these two items apprear under "exposure" as "unkown" and cannot be used but I digress...

How can I configure my webcam to use it's full potential? E.G. 29.9 FPS @ 1920x1080
