With kernel 2.6.38.8, aconnect can connect to the MIDI out of my UA-1000; with 2.6.39, it fails, so it seems likely that it is the same bug.
It's the same bug, caused by this patch: http://git.kernel.org/linus/88a8516a2128
Fix coming soon.
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.
