Hi Alexander,

I've made it clear in my previous mail.

I agree with your analysis for this issue.

I cannot understand what you asked. Would you explain your intent for 
this question?
I have already explain about relationships between channels/rate which 
the devices supports.

I'm a bit negative for this idea when considering about how much work it 
takes for me. If the number of devices which my drivers support was 20 
or less, I would have consider about it. But they support much devices 
than you expected.
