Wait, never mind – I recognize that failing status code. usbaudio2.sys is 
complaining that you have an asynchronous data OUT endpoint but it can’t find a 
corresponding feedback endpoint.

Can you send more of setupapi.dev.log, e.g. from the !!! line all the way up to 
the closest blank line? I want to see what the compatible ID is (in particular 
whether it’s USB\Class_01&…&Prot_00 or USB\Class_01&…&Prot_20, which is to say 
USB Audio 1.0 or USB Audio 2.0 respectively)

I'll try patch this myself also see if it works out.

Ok, patched the linux kernel so that wTotalLength is calculated correctly, 
still the audio gadget device does not load entirely.

Excerpt from setupapi.dev.log:

    sto:                     {Configure Driver Package: exit(0x00000000)}
     dvi:                     Install Device: Configuring device class.

☹

Any ideas welcomed.
