I'm not talking about dummy_hcd. It was a general comment about the gadget
code. I can't give you an example from the top of my head...

Well, I can add the error message but I think that as far as dummy_hcd is
concerned failing it's loading is a bit harsh, isn't it? I mean, this is a
type of user error that can be fixed so why not fix it and just notify the
user of what was done?
