Well, as explained in the other posting, suspend/resume is pretty much different from unplug/replug because a suspended device is still drawing some power from the suspended USB. This way even a buspowered device can keep its state and the host can be sure, it's still the same device which he will resume later on. For unplug/replug OTOH I agree it's a good idea to have the device keep its state as much as it makes sense - but the host _must not_ make any assumption here because the replugged device might just be a different one or might have been plugged to a different host meanwhile.
