Tascam US-144 Mkii and Cubase element

I have a brand new MacBook Pro 2020 that I recently bought. I downloaded cubase element for now to test it out. I then downloaded the Tascam driver for my Mac and everything is attached correctly. However when I want to record with my sterling audio it does not seem to connect. I changed the audio input to the microphone but it will not work. Any thoughts?

Thank you

Hi and welcome,

Make sure Cubase has enabled Mic in the System Preferences, please.
Open macOS System Preferences > Security & Privacy > Privacy > Microphone. Enable Cubase here.
