There is no individual control over power to USB ports on any current RPi. There is only the overall limit for all the ports together. So you can have no control over which device crashes first.
If individual control were available, it would still require a (software) system to work out how much to allow on each port in different load scenarios -- in particular, a current limit would need to be applied in response to an undervoltage on the supply. I do not think this is likely to be a commonly available system in the foreseeable future on normal (general purpose) computing platforms such as the Pi.
