I don't understand. Isochronous transfers have pretty strict transfer-time guarantees. Why wouldn't this work? One reason I can think of is that Iso transfers aren't reliable. But then regular RS232-type serial transfers aren't reliable either. The only other reason is that the USB stack itself has an unpredictable amount of overhead. However I think it should fall within an acceptable range for RT applications.
