I plug in both to be safe.

Of course, unless the device enumerates separately on both ports and is awarded 500mW by the PC on each, you aren't technically any safer. A pint says no enclosure in the world bothers doing this (do you see two USB devices in Windows?).

It's 500mA per port not 500mW. as can se seen here as for what the voltage is I've seen both 5 volts and 2.7 to 3.3 volts speced on different whitepapers. So the worst case power available for devices is 1.35W or 2.5W with a 5 volt supply.
