That is indeed what it looks like.  Of course the USB system doesn't "wake 
up" as such; it simply starts running as soon as the kernel initializes 
it.  One of the first things the resume procedure is supposed to do is 
stop the USB thread (along with a bunch of other threads), to prevent 
exactly this sort of interference.
