[pwc] Quickcam Zoom Silver: grey image and zoom

[Hugo MERCIER <>]

Hi,

The Logitech QuickCam Zoom Silver (Vendor=046d ProdID=08b4) is coorectly
detected by the pwc module and a stream can be grabbed.

But, images are in grey levels. When testing different white balacing
modes, I can make images in red, green or blue levels. It seems like
only one color channel is processed ...

A message on this list on August 2005 talks about a similar problem
(with the older model ProdID=08b3). But I can't get it work correctly.

I've tested older versions (in particular 10.0.7a) without success.

I'm testing with camstream on a 2.6.14.4 kernel

Any idea ?
How can I help fixing ?

Moreover, this cam has zoom control, but setpwc can't set it (neither
pan/tilt parameters). How can I add it ?

Thanks
