This zip contains some MANDATORY INSTRUCTIONS and files that were found in windows\system32 that were supporting this device. If your camera worked on winxp before, and then mystically stopped, it may be because of an installation or updating windows. Either way I cannot test this myself and need people to leave feedback to find out if it really works. Don't forget you must copy these files into windows\system32 and windows\system32\drivers! Definitely read the instructions!
