Near three years ago, I purchased the cheapest USB webcams -actually, one pair- I could find at the time, without taking into consideration whether those webcams worked with Linux or not. I ran one desktop PC with Win2K and one of the webcams was plugged to that box. I quickly found out several things: first, “Made in China” webcams surely are cheap, but that comes at a price of often having no support web site, no physical address of the manufacturer, and no updates to its drivers.
I have used these drivers for webcams under Linux many times before, but never did I realize they were written by one guy. What a feat!
