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,
