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! ;-) [...] > USB hubs should be fun ;-) I've been able to avoid dealing with > them from the programming side so far, but I feel that these days > of blissful ignorance are counted ... 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.
