Thanks for the answer, Peter. As far as I understand You are talking about the second variant when new device is registered / unregistred. How about suspend/resume variant? Is it possible to report -ESHUTDOWN if otg works as a gadget but libusb is trying to access a host or may be bus should be emulated with only roothub on it but not taking control over the bus ? Or suspend/resume should not be used for the otg ?
