[Bug 576806] [NEW] pwc driver philips PCVC740: no picture at all

[Christophe Borivant]

Public bug reported:

Using skype I can capture the sound from the webcam but I can't get any picture.
If the webcam is connected, kopete freeze when trying to configure it.
vlc doesn't show any picture neither.
There are messages in dmesg :
