Well, you received no answer because of the question you asked: if 
nobody is working on such a solution, but nobody knows if somebody else 
is working, nobody will answer your question. So, I guess the absence of 
answer is the good sign that nobody is working on such of solution, or 
that people not working on such a solution are not willing to communicate.

Now, we do not have an in-tree RT USB stack, you would need that as a 
start. Such a stack exists, USB4RT, but the page:

does not look very active (only one release, and never updated).

The usb20rt project looks more promising:
