  # no reason not to enable more than one gadget driver module, but

  # has exactly one of these upstream connections and only one
  # lowest-level driver can control it.

  # gadget drivers are compiled to work on specific hardware, since
  #
  # (a) gadget driver need hardware-specific configuration, like what
  #     endpoint names and numbers to use, maxpacket sizes, etc
  #
  # (b) specific hardware features like iso endpoints may be required
