This raises an interesting question - hotplugging isn't mandated but it is implemented widely. How widespread is it? Eg can we reasonably assume a recent motherboard probably does support it? I thinking of USB daisy chaining - it's possible but hardly ever used, so it might as well not even be in the spec at all -- alan dot mckinnon at gmail dot com
