Buongiorno a tutti, ho configurato la webcam life can della Microsoft su un raspberry di tipo B con SWPI aggiornato alla versione 01.22.62. Funziona tutto alla perfezione solo che di tanto in tanto il sistema acquisisce un'immagine bianca.
La webcam si alimenta direttamente dalla porta usb del raspberry.

Vi allego il file di log e i link delle varie immagini bianche e non

Secondo voi da che cosa potrebbe dipendere??
