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....


Mick
