Hello,
responding to myself, I succeeded in simulating the opening and use of the base driver. In that state, I am able to open /dev/video1 instead of /dev/video0, I get exactly the same capabilities. Please feel free to comment and tell the priorities. Now I reached the first step of the realization, I will do the second step: control the hardware. This step involves the helper daemon to show extended capabilities. I will submit an internal interface (driver<->helper daemon), interesting things will start :)
Note: I committed all the patches in order to save them in a chronological order and to see the final product.
Cheers, Thierry
