CCcam on Gp4.1

I have a question about using CCcam on Gemini project 4.1. I installed both the CCcam and Oscam emu on this image, to be used as an alternative. I have the same setup on the Dream Elite 7.1, which allows me to switch between use without problems. Instead on the Gp4.1 the Oscam works regularly, while the CCcam starts only rarely. Most of the time it doesn't start. Is there any particular setting to use with the GP4? Thanks to those who can help me.
