just came to your page after searching for "linux webcam wiki". What I was immediately asking myself is: What means UVC? I think this point should move to the end of the doc. I confuses the first time reader.
I think adding this would be then enough: UVC (USB Video Class Linux)
I am also looking for references on driver ru5870, for Ricoh family of webcams. I have an issue with that, which I have not been able to solve, and would appreciate to add it to the list, so to see if somebody has the answers I am looking for.
