UR44C Issues

Hi, just received UR44 today. Running it on Mac Pro late 2013. OS: BigSur. Using Nuendo 11.

Have installed and re-installed Yamaha USB 3 driver. Installed and re-installed UR44 Tools - in the order stated on the website (driver first, then tools).

Interface works fine but have no access via DSPMixer (when not using Nuendo). Direct Monitoring is greyed out in Studio setup in Nuendo and “Hardware” does not appear in “Racks” in mixer - therefore have no control over the interface. All I really need to do is switch headphone outs to outputs 3 & 4.

Have also installed all drivers and software on a PC running Windows 10 - still DSPMixer says “no hardware found”. Very frustrating.

Anyone got any ideas? All help gratefully received!

Oh dear! Just in case someone stumbles across this post with similar issues, if you have a UR44"C", download drivers for the UR44"C" and not the UR44. That was the issue! Must learn how to read!
