True as that may be, if there is a bandwidth requirement for the interface to function correctly and the USB protocol being used does not guarantee that bandwidth (only control+interrupt transfers could do it in a meaningful way, and they are rather low bandwidth) then the USB stack would have to allow the driver to reserve bus time, and the driver would have to make a reservation to successfully handle worst-case load. That's not neccessarily a small change. :\ //Peter
