IIRC the pwc driver module of the stock kernel is somewhat broken. Since the decompression has been moved out (which is fine, as signal processing should be done in userspace), only a few modes - which can be done uncompressed - are really supported. Unfortunately, the module does not report an error, when a mode which needs compression is requested, but accepts the request and delivers a blank (grey) frame, and the default is to use compression even for modes which could be done uncompressed (to save usb bandwidth). The second problem can be partially solved by setting the default compression to 0. Unload the pwc module, put an option in an appropriate file in /etc/modprobe.d/ (or wherever your distribution thinks it belongs), and load the module again.
