Not confusing at all. No, sir! ;-)

Well, I was thinking of the case of Anelok acting as a virtual USB keyboard,
which you probably ruled out early on and I just forgot about it.
In the last version of the communications diagram, I mistook the wireless
Anelok-PC blue communication arrow for some kind of USB communication: I
didn't notice the radiating waves from the PC and Anelok, or perhaps
interpreted them as meaning something else, maybe the NSA backdoors! ;-)

I doubt that they're that much fun, but you never know. I've seen ridiculously
equipped 12 port hubs or something like that from cheap gadget shops, which
must really be a collection of hubs combined in the same box because I don't
think the USB standard actually allows more than a reasonably small number of
ports per hub.
