That's good.

Could you please send me the contents of your

BTW, you could try to experiment a bit with volume quirks: See,
mixer.c  search for 2081 to see how it's done for some of the FTU
controls. The volume controls for the FTU are reported in usbmixer to
range from -32768 to 0.

OK, it was just a blind guess as I said.

I was just joking when I mentioned the MOTUs and RMEs ;-) I would
certainly enjoy getting a MOTU Ultralite mk3 hybrid or a RME Babyface
to play around with and personally I will never buy a M-Audio device

But while I'm quite confident that we can get the C400 working (might
take some time though) I don't know wether or not the MOTUs and RMEs
do behave in any way like  UAC1/2 devices at all. I haven't seen a
single report on them, yet.
