But it does shows something going out and coming back in, with 6 ms
elapsed time. That's a long time, making me wonder if your device is not
responding to it.
Odd that on the return from SELECT_CONFIGURATION, it shows the
class/subclass of interface 0, but not for interface 1. The descriptors
all look fine to me.

The checked build is part of MSDN, where you probably got the DDK. I
doubt it will help in this particular case, because I suspect the issue
is between the controller and the device, but it will help later on,
when you start wanting to satisfy USBAUDIO.SYS and SYSAUDIO.SYS.
