Hi Stefan,

Thanks to get these logs. It's really helpful to me.

>> 1.They have both iPCR/oPCR.

They have no oPCRs, against my guess.

I wrote snd-oxfw with an assumption that devices have iPCR/oPCR. So I 
must write some patches for my last RFC:

http://mailman.alsa-project.org/pipermail/alsa-devel/2014-January/071820.html

>> 2.They can respond to 'SINGLE' subfunction of 'AV/C Stream Format
>> Information' command.

OK. They supports this subfunction.

>> 3.They can respond to 'LIST' subfunction of 'AV/C Stream Format
>> Information' command.

OK. They supports this subfunction. The snd-oxfw can detect 
channnels/rates for these devices instead of hard-coded parameters.


Thanks
