Comment 35 for bug 293259

With Interpid Ibex (ubuntu 8.10) I found the solution.
Here I repeat myself from
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/205970
I hope it helps for many.

  On my Interpid Ibex / Acer eMachine e520 the solution found at
  http://forum.notebookreview.com/showthread.php?t=291894
  solved the case.
  Since it is forgotten at each reboot you can make it start automatically as

  sudo gedit /etc/modules

  add line

  uvcvideo

  sudo gedit /etc/modprobe.d/options

  add line

  options uvcvideo quirks=2
