.... You've also had my attention in the past, if I recall I have you 
tips about not using cx_write, instead using cx_set/cx_clear.

Your latest patch still doesn't have those changes btw. ;)

I disagree with everything you've just said, but that's just my opinion.

Did I not try to help you? The one piece of initial feedback I gave you, 
you ignored. (see my opening statement).

I'm always willing to help people, but they also have to demonstrate 
that they are applying themselves, doing basic research, asking specific 
questions ... rather than, here's my patch - and What's Wrong with it.

So port the mcentral.de details into the kernel, I doubt they'll be 
significantly different.... we're talking about adding support for an 
existing card, it's not a lot of engineering work.

... and your efforts are valuable.

Markus (mcentral.de) is paid to work on Linux, just to be clear.

Your last message on that thread said: "xc2028 2-0061: xc2028/3028 
firmware name not set!"

You could of asked a second time before taking the opportunity to vent, 
and taking the community to task.

Showing patience and perseverance is what most other newcomers demonstrate.

Whether we have 3 people or 30, it's never enough.

In my experience, people who join the list then vent all over it are 
rarely around long enough to make a difference. They often think they 
know more about the community than the community itself.

On the other hand, the people who join and ask well thought out 
questions, describe their failures and working assumptions, then 
demonstrate a willingness to learn attract a mentor very quickly.

... just my opinion of course :)

If you want to make progress with the leadtek card then another look at 
the feedback I gave you, then approach the group again with a more 
insightful email.

Maybe someone will help you then.
