I have a UR22 mkII that has worked flawless with Cubase since the day I got it.

I use it on a second workstation; my primary workstation has cc-121, but I cannot lug them back and forth and I didn’t want to invest in a second cc-121.

So I got a couple of CMCs. I installed the tools/driver and now the UR22 doesn’t work. I uninstalled and reinstalled the UR drivers 3 times to get it to work, but that cut off the CMC functionality.

are these 2 products incompatible? Is there a special sequence in which I need to install the software for each?

I’m using a PC on windows 10 latest version. i7-7700. Cubase 10, latest version.
