It works! :-)

Are there any limitations envolved with the quirks you do here?
In mid-term I want to checkout if I can use the 192kHz sampling rate
for research purposes. ;-)

What is .ifnum 4 doing, which is now QUIRK_IGNORE_INTERFACE?

I'll post a kernel-patch which you could propably take upstream from
another email-account...

Thanks again, it is really fun to hack the kernel again!
