Well, I can do nothing with luvcview... it is a complete black screen :-( How can I raise the brightness ?
With kopete when I try to configure the cam, I have a green screen on the GUI and a error message: "read error 19, Aucun périphérique de ce type" (sorry if it's in french) So, if I well understand, my cam should work and you have no idea of why this is not working :'( :'( In that case, thank you for your help even if it is not working at that day....
