Hi Mike
Like all the other computer based instruments (Wersi, Lionstracs, TMS etc) it will most likely be a standard desktop computer inside, (Without the case of course) and so will have all the latest features, including USB 2.
If it helps to put your mind at rest, the B4 VST has been used without any problem on Wersi instruments since they were introduced in 2000. (Wersi instruments run on XP)
