Getting the voltage of more than 6.5v from the USB port of NUC damaging the connected devices.

[shabaz]

Hi,

I am using a NUC system to power and communicate with arduino through the USB port. The NUC is placed in a vehicle. The power to the NUC is supplied with the help of a inverter from 24 V batteries. As we observed the arduino uno board getting damaged  we checked the voltage we are getting from the USB port and found more than 6.5 volts. How this can happen and how to avoid this problem of getting higher voltage.
