You may have to draw us another diagram. :-) One thing that I belatedly realised after our previous discussion of the Y-Box was that the hypothetical but not actually described scenario of using Anelok as a USB peripheral as well as a host depending on what the Y-Box has connected, which is admittedly awkward, reduces to the Y-Box effectively behaving like two hubs in one: PC -> Y-Box -> Anelok Here, the Y-Box provides bus power like an unpowered hub. Anelok -> Y-Box -> Keyboard Here, the Y-Box provides its own power (actually from the PC) and acts like a powered hub: the PC is the power source, not batteries or mains electricity or whatever. So, you have an unpowered hub and a powered hub in the same box.

You're not the only one having fun, Werner. ;-) It does get me thinking about the notion of a smart USB hub, though, despite my instinctive dislike of the technology.
