Webcam Creative Live! (VF0470) e Ubuntu...

Ho recuoerato questa webcam che avevo acquistato anni fa; il kernel la
riconosce correttamente:

Se apro VLC e apro la 'periferica di acquisizione' (/dev/video0), funziona
perfettamente.

Ma ne Cheese!, ne i browser con i vari servizi di videoconferenza la vedono.

Perchè?! Grazie.

Il modulo per quella webcam sembra essere giusto (ov519):

Nessuno dei due...

> Molto strano in effetti

Comincio a pensare che, avendo una rioluzione troppo bassa, venga 'schifata'
