I don't want to start FUD. I just note that USB driver developers may care
least about playing well with scsi, not just rare, but really rare in the
consumer marketplace .

But, I'd be happy to hear from someone that there is some "layering" that
makes my speculation sheer nonsense. 

(Not to digress, but how could I make my USB devices share an interrupt
among themselsves, Or does the inquiry reveal an embarassing ignorance of
incest taboos?)
