Actually, I don't want to be too hard on Startech. They did give a
knowledgeable answer about the UASP support in their devices and that's
actually great and really enough to know if their stuff works in Linux
or not. Personally I think it'd be great if companies went with that wrt
Linux, i.e. just say something like "we support standards x, y and z so
if Linux supports those it'll work fine." At least when it's a question
about standardized protocols.
