Unable to list outputDevices when Traktor Audio 2 MK2 is connected

[bcardiff]

When I plug my Traktor Audio 2 MK2 device and call [EZAudioDevice outputDevices]

I got the following error in the log Error: Failed to get frame size ('!siz')

From there I am unable to select it as output device even if I [EZAudioUtilities setShouldExitOnCheckResultFail: false];

Is there any workaround available? Thanks
