Nvidia Shield with iRig Duo Pro

[dwrae]

Our driver follows the USB specification to set the 'USB alt setting' (excuse the tech talk) to 0 after each use to free up USB bandwidth for any other app/software that wants to access the USB bus. This is usually not a problem, but only IK Multimedia's hardware seems to suffer from this. Using one of their other devices, it actually does not work when we do NOT change to alt setting 0. So I guess it's time for a preference option! :)
