I have an older webcam by logitech. It is round like a ball mostly white with dark grey as the eye and as the top (mohawk shape) with a white buton in the center. it sits on a dark grey base that has three point. M/N:v-num14, p/n:861092-0020, s/n:LNA41732268. What is the name and where can I find the drivers. Please help.
