I do have an usb dump of Windows initializing the thing and can/will share and/or generate new ones if you/others want to have a look. It hasn't helped me so far, problem being I dont really know what to look for in the first place.
Although I doubt I'll be able to make more sense of it than you, it would be interesting to have a look at, perhaps it can be useful.
What might also be interesting if you don't already have a dump of it is Windows actually starting a playback stream.
IIRC you start getting hangs accompanied with "cannot get/set freq XXX to ep Y" (or similar) messages when you try to open both. For a single interface at a time, those messages went away by adding the small delay, but adding more delay doesn't help with the case where both are active.
So to me the evidence seems to suggest it only supports a global frequency for the device, instead of per interface. Which, considering what the device is, seems quite reasonable.
Yes, I agree.
