Yamaha Steinberg USB Driver v3.0.5 installation problem

Hello,

I have a Yamaha THR5A amp and MacOS 11.2.3.
I followed the instruction to install “Yamaha Steinberg USB Driver” v3.0.5 and Cubase LE AI Element 11.
After the installation, Audio MIDI setup does not contain the driver and Cubase does not show the driver either.

As another data point, the yamaha THR Editor app can detect the Amp and show it as connected.
Can you please help?

Thanks,
Jonathan

Solved. It was Security preventing the “Yamaha Steinberg USB Driver” from being installed properly.
