cannot use USB port when using Cubase


When I use the dspMixFx for my UR242 on my windows 10 machine everything works fine.
But as soon as I start up Cubase Elements 9 I get the following message:

cannot use USB port, it’s being used by another application

I have updated all drivers but that didn’t change a thing.

Does anybody have an idea what’s wrong?

Hi, did you get this sorted as this has happened to a friend of mine. He just cant get the Ur242 and Cubase taliking to each other… same message. Thanks
