For those who want to use the FaderPort Classic with Cubase 10 (also works in 9.5) this is procedure I followed. This works on the Mac 10.13 and 10.14. There is also a driver for Windows.
Go to this page, on the bottom there is at the bottom but look for a link on the page for "Show/Hide all versions of Software Downloads for your OS. Then click on that link. Then scroll down and you will see
FaderPort Control Installer
Download that and run it. It will come up with a box for what DAW drivers you want to install. Make sure Cubase is checked. This was only made available in July 2018. I think you need Cubase 9.5 and above. I also tried this on the new FaderPort 2018 and it did NOT work. It is only for the FaderPort Classic.
Hope this helps.
