Found something interesting. Seems like this can be used:

https://msdn.microsoft.com/en-us/library/windows/hardware/ff537752(v=vs.85).aspx

Anyone familiar with this? What's the intended usecase for this if driver
is not supposed to set default stream format, as Tim pointed out.

Cool, thanks again.

Just out of curiosity, if I had a case that mandated support for other
formats too, what options would I have? Can a driver specify the
channel config it wants the endpoint to come up in at the time of
endpoint registration?

No.  The application is expected to be the ultimate authority on what
format it wants.  Your hardware is merely a slave to the desires of the
application.
