Surely for a data bus that is assumed to have multiple devices using it, *all* data has to be time-stamped in some fashion. If not, then that means that nobody using a USB QWERTY keyboard with a USB MIDI interface would be having success, since it would mean that there's no way for USB to appropriate serialize events generated by different devices destined for the same software process. I've never been impressed with USB, though I use it a lot (I have a three devices attached to my PC and four attached to a USB hub). I just don't use it for more than one time sensitve task (my mouse, which is plugged directly into one of the PC's USB ports). -- David W.
