On a related note, I've found unplugging a FireWire device from
Quicktime Broadcaster will then prevent that device from being detected
until I reboot the machine(s) in question. This could be related to
your problem. I sent a bug report the subsequently received a reply
'it works here' (sigh) so I'm getting a test case together.
After reading your post this only confirms that there are still holes
in the Firewire implementation.

Jose.

Subject: FireWire CoreAudio Recognition
I am using Core Audio to communicate with an mLan audio interface via
FireWire. Everything works fine except for one problem. If I turn
the FireWire device off and then back on without rebooting the
computer I can no longer talk to it. The Apple System Profiler shows
the FireWire device fine. Audio MIDI Setup doesn't see the device and
it's not available in Core Audio. If I unplug the device FireWire
cable and the plug the FireWire cable back in then the device is fully
recognized and available via Core Audio.
Can anyone tell me what's going on here ? Is this a Fire Wire or Core
Audio problem ? Is there any way to programatically cause the
equivalent of unplugging the Fire Wire cable and plugging it back in
so I can use the device ?
Thanks,
Jeff Z
