Your questions are interesting, and I would be interested in the answers as
well. Unfortunately, I don't know the answers to them.
I can tell you that your driver is called by the MIDIServer. The MIDIServer
is run on demand by any app that registers with CoreMIDI. Your driver will
be loaded by the MIDIServer.
It is at:
/System/Library/Frameworks/CoreMIDIServer.framework/MIDIServer
You should be able to set up a custom executable in Xcode and debug your
driver plugin with the MIDIServer as the host (then Xcode will launch the
MIDIServer under gdb for you). Or you can probably attach to the MIDIServer
with xcode as well.
I believe that the SampleUSBMIDIDriver::MatchDevice is actually called by
other code in the sample driver, after it has registered for USB
notifications with IOKit. If you are HID based, you may have to rewrite all
of that infrastructure code in the sample to find your device.
I hope this helps. Perhaps someone who is more familiar with the lifecycle
of the MIDI drivers will pipe up and add to the foregoing.
Best regards,
