You need either [pdp_v4l2] from pidip,

or use LD_PRELOAD to use /usr/lib/libv4l1.so as an adaptor between the 
v4l1 driver system used by [pdp_v4l] and the v4l2-only interface of the 
uvc.ko driver for your UVC camera.

Logitech Quickcam Pro 5000 and later use the UVC protocol with uvc.ko.

Logitech Quickcam Pro 4000 and earlier use the Philips protocol with 
pwc.ko. (well, there were at least two other generations of Logitech 
before they switched to Philips.)
