Hi dear Cubase community!
I have the following issue: just installed a RME UCX audio interface, upon starting Cubase I have the message “New Audio Drivers Found - Cubase has detected that new audio drivers are available on your computer. Please select…”
I select ASIO Fireface USB, and then I get the following error “The audio driver could not be loaded”.
I updated Cubase to the latest 13 version and still no success.
If I bypass the error, Cubase loads and I can set the Fireface Asio USB driver under Studio → Studio Setup. But on next Cubase start I get the same error messages. Also Cannot load my projects, I am only able to create new files.
Any help is highly appreciated! Thank you!
Using also an RME Fireface UCX (with USB connection), I never experienced such an issue, even if there has been other ones. So, how is your UCX connected (USB, FireWire) and can you post a screenshot of your Studio > Studio Setup > Audio System panel ?
Beside this, and as your setup seems not consistent from a session to the other, I would try, at first, to uninstall everything RME related and reinstall it, with administrator rights, of course (or the equivalent, with a MacOS system).

Thanks for your reply! I am using it with USB connection.
I reinstalled Cubase, drivers, nothing.
Then Updated firmware, nothing seemingly.
Then uninstalled and reinstalled all USB drivers too, tried some settings in the USB Settings - Options - WDM Devices (reduced the nr of devices from 3 to 1.)
Also I had a Toneport UX2 Asio driver showing up in the Asio drivers list - I manually removed it with Regedit.
After that, guess what…?! Now it works. I hope it will stay like this. I’m not sure which step solved the problem, but I’m happy it works.
And your suggestion of reinstalling (As Admin) is also very good! I used it with other problematic interfaces (Motu Ultralite Mk 4). I hope my new UCX will not be problematique though. 
Thanks again!
