Good point, so kind of below code should be added to usb_suspend_both
to handle the situation centralizedly:
if (!PMSG_IS_AUTO(msg)) {
if (hdev->do_remote_wakeup && status == -EBUSY)
pm_wakeup_event(&hdev->dev, timeout)
status = 0;
}
For hub devices, the 'timeout' should be a bit long since khubd has been
frozen.
