Here are the instructions from cyberface on how to get a webcam working on a Hackintosh netbook. Thanks for info cyberface! Here is the link to MsiWind forum.

Easy hack - get a terminal open, get root, then go to the following folder: /System/Library/Extensions/IOUSBFamily.kext/Contents/Plugins/AppleUSBVideoSupport.kext/Contents Edit the Info.plist - scroll down until you find the dictionary called 'VideoSupportRev182' - there will be two keys in there, one called 'idProduct' and one called 'idVendor'. Convert the hex USB values above into integers and replace the numbers (you may want to take a backup of the file...) - in my case, replace the value in the 'idProduct' key with 25280, and the value in the 'idVendor' key with 3141. Save the file, no need to reboot or rebuild kextcache, just launch Photo Booth and the webcam will immediately work.
