I have already submitted this to Parallels, so its FYI for the rest and a small addition for Parallels. I had just restarted Parallels and had then gone into MSM to configure my Philips ToUcam Pro II. The sound worked perfectly, but on the next step when I selected the web-cam for the video, parallels crashed completely disappearing from the screen. The only error message was from OS X crash dump Part below. @Parralells: On restart of parallels, I could no longer connect to the webcam. I got the device is in use message.
