I've been trying out a Logitech Quickcam Pro 4000 via usb on our single
machine node under Linux. It uses the pwc philips module and requires a
pre-install of usb-uhci module. For full picture size (640x480) you'll
also need to post-install the pwcx-i386 module (separately supplied, as
described in above email).

It comes with installation CDs for Windows so I guess it works that way,
but I haven't tried it.

Its downsides for me are

1. doesn't work with "normal" vic. It _does_ work with openMash vic
(which I quite like for other reasons) however openMash vic uses a lot
of cpu whenever there are active video streams i.e. you've clicked on a
thumbnail to open that streams window

2. the size of 640x480; when that is halved to fit into a H261 frame it
leaves a fairly wide border around the image i.e. 320x240 image in
352x288 window

3. I can't achieve frame rate better than 10fps under openMash vic. UCL
vic achieves 30fps but no picture.

Maybe someone is interested in fixing either of the vic programs?
