Tvheadend

Good friends, I have an Avermedia tuner pci card and I would like to use it in Linux (Debian) but it seems that it needs drivers and I can't find a way to make it work.

The tuner could be from the year 2008. I have installed in Debian tvheadend but it does not recognize the device:

The output of the lspci -knn command shows me this:

The system recognizes the pci card but for tvheadend it is as if it did not exist. What I would not know is how to install appropriate drivers or find them for this model of card. Can you help me?
