Thanks. That's good to know. Is this bug still in the sample code? If
it is, one of you should still file a bug about the sample code.

I've encountered the same problem, which was due to a bug in
USBDevice::OpenAndConfigure() in
/Developer/Examples/CoreAudio/MIDI/SampleUSBDriver/Shared/
USBDevice.cpp
The problem is that the code does a SetConfiguration(...) on the
device, regardless of the current configuration value, which in turn
causes all existing IOUSBInterface objects attached to the
IOUSBDevice to be destroyed and reinstantiated.

No. That's not supposed to happen. Can you file a bug?

I observed that when I click on the AudioMidiSetup MIDI pane
for the first time, the engine of my USB driver gets stopped and
restarted (which causes any playing audio to temporarily stop).
Is this expected behavior?
