    If your BoB is POWERED by USB (caps, to emphasise that the BoB is only powered by USB, but signalling is still by parallel)...

    Keep it simple. Use the power switch to power the stepper drivers. If they are de-powered then the motors ain't moving. Even if the BoB is powered via USB, if the switch is off, the steppers won't move.

    You're more likely to introduce problems if you try to switch the BoB power supply.
