No.  Now your into USB hotplug, aren't you? But if this is related to
suspend/resume, then it's probably answered by
https://www.kernel.org/doc/Documentation/usb/power-management.txt

Sorry for only pointing to further reading, but I'm definitely not
capable of answering any better than the experts who have written those
documents.  And I seriously doubt anyone else is either - with the
possible exception of those experts.  And they shouldn't have to repeat
their answers when they have taken the time to write excellent docs,
should they?
