Not sure from your message whether
[a] your driver is failing to load in the first place (which would point
to CFPlugIn not being happy ... there are two places in the Info.plist
and one in your code where you have to have entered your UUID) ...
or
[b] your driver is loading, but not receiving service-published
notifications. Please try setting a breakpoint at
USBDeviceManager::ServicePublished and tracing from there to see what's
going on.

I'm developing a MIDI Driver for a vendor-specific USB MIDI device.
I have cloned the SampleUSBMIDIDriver project, tweaked the info.plist
appropriately, and everything builds fine. I place the resulting
bundle in
/Library/Audio/...
But I can't get MIDIServer to instantiate my driver or call its
MatchDevice
method when I plug in my USB device.
There is no obvious problem in the info.plist. I have generated a new
UUID,
the CFPlugInFactories property is correct (e.g. It matches the export
of the
bundle's object module), etc.
How do I get MIDIServer to instantiate my driver?
Thanks in advance...
