Hey, I was never able to take advantage of the rawusb mode in the usx2y driver with JACK2. Ever since I upgraded jack I get this message:
ERROR: cannot register object path "/org/freedesktop/ReserveDevice1/Audio1": A handler is already registered for /org/freedesktop/ReserveDevice1/Audio1
Here's the complete log:

Dmesg does not give any information on this issue. Is there any debug mode that can tell me what's happening with jack? I really like the fact that the server does not stop after an xrun occurs and although I'm not sure if this is actually the cause of my metronome drifting in Ardour I wish I was able to use this rawusb mode.
