any discussion leads nowhere about it, there are so many mails out
there everyone can fish some out of them and put things into every
light someone wants to see that issue.

I could start that I initially asked how I could solve that problem
and there are also logs available.
That I don't really trust several v4l/dvb developers is because I've
been pointed to a wrong direction initially and that's why I'm also
very skeptic about listening to several people here.
Sure I also made some mistakes but I was the one who came up with the
code the whole time where others were telling me stories that I should
better look at some other examples which do not solve that problem.
Also during that time other devices came up which again had different
requirements and that's why I redid some parts again, if everyone
would have agreed during the first approach to get that work in it
might have turned out to a community work in the end but the current
way how many things work out are not good.

If a company comes up with a new hardware AND with a driver which
would cover the parts which are not supported by the API some people
would fight against it and write that they know everything better.

I also remember one of the first few emails I received and it was like
you're doing it completly wrong without a technical reason why. In the
end there was nothing wrong with it - several other drivers which are
in the linuxtv repository just do not fit all requirements yet and
would need some updates if someone keeps the changes local to his
drivers it's just fine.
