Yes, but we can't force a dependency on all users without understanding
if this dependency is really needed.

Could you try to understand *why* udev makes it work for you?

One guess is that udev has some rules that makes your USB capture
device accessible to non-root users. And since tvheadend runs as its
own user, this might explain it.

Could you have a look into this ?

Thanks,
