[SOLVED] TVHeadend not detecting reciever

[Tutzelki]

Hi,
I run into a little problem when trying to configure tvheadend from xbian-package-tvheadend.
It did not detect any "TV adapters". After searching for ever for a reason why my HVR-930C would not be detected even if it was loaded properly (checked lsmod), I finally run tvheadend not as service but manually to see the output. And there it was, some permissions to the video adapter were missing. If you have a similar problem just do the following:
ssh into your raspberry

Terminal

sudo stop tvheadend #if it is already running
sudo gpasswd -a xbian video
sudo start tvheadend

This is what I did it might be different for different adapters.
Additionally the firmware for my adaper was missing so I had to copy it from my ubuntu workstation.

edit: Changed initial work arround to permanent fix
