Sorry, Mike, you are still missing the point...
What's the speed of transferring a 40kb file under USB1? (that's all most styles are). At 1.5MB/sec?
Yep, a tiny fraction of one second... How much faster will it be at USB2? Who cares.

1/100th of a second is fast enough!
Just do me ONE favor... explain any use of your arranger that needs data transfer at faster than a tiny fraction of one second...
Then start bitching at Yamaha to put eSATA interfaces on their arrangers (faster MUST be better, no?

) and stand back as they laugh their heads off at you!

Just like me...
