Any hints? It seems like my callback function is not being called, but there is information being published into the corresponding topics. Is there any way I can "see" what is going on after receiving the data and before the callback (which is not called), or if the node actually receives the data?

Thanks!

EDIT: I finally found what the problem was. It has nothing to do with the software, which is perfectly fine. It seems that my cameras were connected to the same USB 2.0 bus (but different ports), so when I tried to get RGB + Depth from both of them simultaneously there was not enough bandwidth for them and thus there was a collision.

Having the two cameras on different USB buses solved the problem :)
