As far as I can see, that lists 3 “problem threads” on the first page which 1 was user error, one was “the bloody USB cable”, and one was a Mac-user who can´t RTFM…
I don´t think that is anything representative, (nor does it indicate a “common” problem) - to support any of your above statements… IMHO
Or maybe I have a different intarweb
I had worked with a Audiobox before, and though I think it´s not a good interface, it does work with Cubase.
