Just out of curiosity: does using of isochronous transfers improve
throughput compared to bulk?  I'd be rather surprised if it does...

Re. your patch, I'm missing the point of having multiple iso urbs,
especially since you use an interval of 1.  Why not use iso frames
within a single urb where the bulk version uses separate urbs?

Or am I saying something totally stupid?
