Actually, we know what's present as soon as a bus reset completes, which is measured in microseconds (1394a) or 300ms at worst (1394-1995.) There is the case of a device that has to boot and isn't initially available, but it will issue a reset when it comes online and our subsystem will do detection again if needed.
