cc121 does not work !

Hi ! I bought today a brand new cc121 and does not work with Cubase 10.5. I have Macbook Pro, Mac OS Catalina, i downloaded the latest drivers 1.7.6 I installed them correctly many times, as in the instructions, but still to no avail. Only the indicator “cubase ready” flashes and noting more. I have also USB sound card UR28M and midi keyboard and they works perfect, but with cc121 i have no success ! Мay be i need to return this product !?

Mac OS Catalina is not supported yet.

However, CC121 on Mojave works great!
