I guess there are multiple "modalities".

- some users don't use a gadget driver and expect host mode to work 
(they fail)
- some users use a gadget driver and host mode (apparently that works)
- some users use a gadget driver only (they work)

I'd  like to avoid having multiple kernels.  (and to be honest, I'm not 
convinced
just convince I can get the right behaviors by changing the .config; I 
assume
you mean .config and not Kconfig...  I don't think it works but I'll try 
it out)
