Hi Alan,

It woun't add too many complications but I would prefere not to do that.
My goal was to simulate as much as posible "real" USB connection so the
is_super_speed flag simulates the USB port you connect to, HS/SS. When
working with a real host if you connect a HS device to a SS port it
connects to a HS root hub but the SS root hub is functional and
registered. So I don't see any reason not to register it for dummy_hcd as
well.

ok, thanks. Will update.
