After some research I found out the problem.. it was so simple.
The only detail that was missing was the v4l2 support which is accomplished by installing the "pwlib-plugins-v4l2" package.

I found it out because Eckiga didn't give me the v4l2 option during configuration, only the v4l option. But the uvcvideo is only compatible with the v4l2.

That's it. Hope everybody gets their camera working!
