Merci,
c'est difficile de tout comprendre, mais la curiosite a toujours du bon,
donc, si je comprends, (je tente...) je me dois de patienter, ceci dit, 
j'ai remarque en cherchant sur le net, que cette cam VC302+Ov7620 
0ac8:307b fonctionne sur un kernel 2.6.22 avec le gspcav1, (je suis avec 
un 2.6.18 ...etch)
...a quand une reelle collaboration des fabricants entre eux pour une 
utilisation simple et moins mercantile...
cependant vous faites un travail enorme pour le monde libre, bravo,

a bientot pour d'autres tests,

Jmarc
