I just upgraded to 8.5.15 from Cubase 6 and can’t get the UR44 app to even open!!
Keep getting error: “Cannot use USB port: it is being used by another application.”
I don’t have any other apps open except Google Chrome.
Cubase 6 the UR44 app works fine.
Any assistance will be greatly appreciated.
UPDATE:
The problem was also that I could not get any signal into Cubase 8.5.15 from the desktop audio thru the UR44 (everything works fine in Cubase 6). I loaded latest drivers uninstalled the UR app and reinstalled the new UR44 driver and application and now I can hear the audio from the desk top and see signal levels on the Cubase 8.5.15 channel strip. Whether this was the root cause of the issue, I dunno but it’s working now.
