I have a very similiar configuration except I have VSE 2.7 and it runs fine.
In my humble opinion you are better off using full volume minidisks anyway.
Time was when dedicated devices made sense from a performance standpoint that time is long gone.
Let VM do what he does so well ... handle the hardware.

I can't help you with the fine print, but if the difference is the code
path that's gone thru for mdisks vs. dedicated or attached, perhaps you
could use full-volume mdisks.
