Hi,

 

it might be a stupid question but I can't get a final answer, therefore, sorry in advance.

 

I'm wondering wether this defines an USB audio interface according to the USB Audio Class 1.0 or 2.0?

The defines in audioclass.h seem to define an UAC2 interface but then the device is only set to Full Speed instead of High Speed. Enabled High Speed mode is a feature of UAC2 while Full Speed is a feature of UAC1. This confuses me a bit. Or is this example indeed a UAC2 implementation that is only limited to Full Speed because it only handles a full-duplex stereo stream?
