Con lsusb e lsmod | grep videodev vedo che la webcam è riconosciuta e i driver uvcvideo sono installati.
Quando però vado nelle impostazioni skype e provo la webcam, i paramtri uvc camera con il relativo id son giusti, la webcam si accende ma lo schermo è nero.
Cercando ho trovato questa soluzione (e sembra anche l'unica):
precaricare questa libreria con LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype da terminale.Purtroppo nel caso mio non funziona.
Incollo un po di output per darvi un idea:
