You can turn indexing off for blue tooth devices but for USB, the way it works as I understand it is ... when you plug the thumb-drive in it indexes at that time and then builds the voice commands to access it. There is, however, a button to force another indexing of the USB device.
So, you can and probably should turn indexing off for blue tooth but if you leave the USB device installed it shouldn't re-index unless you force it.
