Tvheadend

Hi,
I'm trying to descramble tivùsat channnel with the DVBSKy S960C and TeleSystem SmarCAM (produced by SmarDTV). tivùsat channels are encrypted with Nagravision 3, but - by now - that's not the point of my issue.

I'm using the DVBSKy S960C mainly on my Raspberry Pi 3 B with TVHeadend (self-compiled, Build: 4.1-2414~g041b949), and also on Ubuntu 16.04 (I think that the build is the same as the one on the RPi).

In the DVB Imputs>TV Adapters tab I see the CI adapter as ca0. Inserting the CAM module the ca0 atapter status change from slot empty to module present. The issue comes now, after ~10 seconds the status change back to slot empty.
If the CAM is inserted at the system and TVHeadend CAM, instead of hot-plugging it, the ca0 status in TVH is always slot empty.

Here we can see the real issue: the CAM is not responding. I've installed the the DVBSKy drivers. I’ve also tried compiling both DVBSKy media build, and standard media build (by LinuxTV), but the error returned it’s always the same.

I’ve read many topics around the web, but none of that helped me.

Like:
https://tvheadend.org/boards/13/topics/20014 (this scares me)

https://www.mail-archive.com/[email protected]/msg105806.html (this talk about a CI+ CAM, but it’s similar to the one i own, and also the error it’s the same)

Thaks in advance.
