I was playing around as i was baffled by the 2 devices showing when i plug in the device via USB.
So here’s what i have done to get it working for my scenario (i.e. when i plug in the device i see 2 x devices listed then one goes away when i start cubase)
On Mac i launched cubase and the device type USB (ur22mkII) disappeared leaving just the one of no type (as seen in settings>sound)
I then ran from terminal
to list the loaded extensions - i noticed the following was loaded jp.co.yamaha.driver.YamahaSteinbergUSBAudio so i unloaded it using the following
sudo kextunload -b jp.co.yamaha.driver.YamahaSteinbergUSBAudio
this resulted in there being no ur22mkII devices listed in settings>sound and when cubase offered me an interface to select there were no ur22mkII’s available so i continued without selecting any - then i returned to terminal and loaded the extension again
sudo kextload -b jp.co.yamaha.driver.YamahaSteinbergUSBAudio
which then showed the non usb type UR22mkII listed in settings>sound again and i navigated to cubase studio setup and selected the asio device ur22mkII from there and i could hear audio and my mixers were displaying activity.
i assume i’ll have to do this every time unless i can find out what is going on but at least i can use the ur22mkII again with cubase…
Its like the Mac doesn’t associate the device with the driver/ext or something…
