Title:
  webcam not detected in ubuntu 11.04

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I found some bugs in Ubuntu 11.04 beta 2. This one is about my
  integrated webcam not being detected.

  My netbook is the new MSI wind U270. This one:
  http://www.laptopshop.nl/product/127746/msi-wind-12-u270-004nl.html

  I found a number of links, like this one:
  http://ubuntuforums.org/showthread.php?t=1629538
  which mentioned I could find information about my webcam with commands like lsusb, lsmod, dmesg.
  If I run gstreamer properties in the terminal, it opens the "Multimedia Systems Selector". I can then test the video input, and get the following message:
  [quote]
  Video for Linux 2 (v4l2): Cannot identify device '/dev/video0'
  [/quote]

  And this is the output from the terminal:
  [code]
  ~$ gstreamer-properties
  gstreamer-properties-Message: Skipping unavailable plugin 'artsdsink'
  gstreamer-properties-Message: Skipping unavailable plugin 'esdsink'
  gstreamer-properties-Message: Skipping unavailable plugin 'sunaudiosink'

  gstreamer-properties-Message: Skipping unavailable plugin 'sunaudiosrc'

  system error: No such file or directory]
  [/code]

  This is the output from lsusb:
  [code]
  ~$ lsusb
  Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
  Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

  [/code]

  This is the output from lsmod | grep video:
  [code]
  lsmod | grep video
  video 19438 0
  [/code]

  After installing cheese, it either gives me a message that it can't find a camera (no '/dev/video0') or it just doesn't open at all, and I have to force quit it.
  I posted this is a forum, and was told to file this as a bug report, I hope this is useful.
