Well, no matter how it "scales" it needs to be done in userspace, like
usb_modeswitch does.  We made that decision a while ago, and it is
working out very well.  I see no reason why you can't do it in userspace
as well as that is the easiest place to control this type of thing.

I thought we had a long discussion about this topic a while ago and came
to this very conclusion.  Or am I mistaken?

thanks,
