Update: I used the Apogee Duet 3 for a while today, for the first time, and no overload spikes as yet! I’m also using the PC case front USB (I never usually use that one). Do you think specific USB ports matter? Just another variable to wonder about maybe.
I just have the overload problem of Disk Cache when cycling.
That is another issue, which others seem to have: Disk cache overload in cycle mode - Cubase - Steinberg Forums
