It's great to hear you know the cause of this. Thank you very much! Armed with that information, I've found that replacing '#ifdef CONFIG_PM' with '#if 0' and commenting out calls to usb_autopm_{get|put}_interface() inside sound/usb/ gets me a working MIDI out on kernel 3.4.18 for now, which makes me happy. If there's a proper patch I can usefully test, I'd be very glad to know about it. Thank you. Colin.
