Yes, I keep thinking about such a thing for years now...

Instead of a âgadget HUBâ which would have to do a lot of translation of
headers and requests, I was thinking more of making USB composite functions
even more structured (ie. adding callback for per-gadget setup,
per-configuration set-up, etc.) and then creating a composite layer which
would be feed with a trivial structure describing which functions are to
be included in which configurations.

Like I've said before, that's almost what Android does, expect it does
not support many configurations.
