It's too short and the new USB stack will introduce an ABI breakage. For that, all drivers written for the old USB stack need to be rewritten and I guess, we need to take care about 3rd party developers and inform them in advance about that massive change. I would not wonder if this will never get MFC'd but I don't know actually. HTH Volker
