The pwc driver returns a v4l2 installation.
The gb.v4l component can't handle v4l2 complet/correct but only v4l1 ATM

I have the same problem with the philips cams, i.e. PCVC645, and flash (adobe) 
and i'm using flashcam package http://flashcam.sourceforge.net
A project to make Adobe Flash for Linux support V4L2 webcams or video devices.

It's using a modified vloopback from the motion project.
This is in use for webcam on the intraweb site.

Best regards,
