You misunderstood. I meant that attempts to suspend a USB device without first suspending all its children and interfaces can't happen when doing a global suspend. That's still true.
Your problem occurred because even though the PM core did _attempt_ to suspend the new children added by Greg's patch, it didn't _succeed_ because the patch did not provide suspend or resume methods.
