Dear Laurent,

sorry to bother you with this but I am stuck now for a couple of weeks trying to
make the LI-5M03 camera to work on the bb xm rev c. I am trying to build a
system to track neurons under a microscope. at the moment, I have the kernel
3.7.3 installed w the mt9p03 driver (I believe that it is a version that you
made) compiled as a module and ubuntu 12.10. The module loads fine, no complains
but I do not have /dev/mediaX or dev/videoX or any /dev/v4lXXX

I wonder if there are any tricks to have the device properly loaded. My linux
kernel and rootfs came from here:

thanks immensely for your help!
