You use both. One is for data and the other is to provide the device the extra power it needs.

Some USB powered devices need two USB connections in order to get enough input power to run. EG USB2 has a max of 500mA per socket so if the device needs more than 500mA then you need to connect two USB2 sockets to get it to run.

I guess this is the situation unless the external drive also has a power adaptor.
