Pin 1 is V_BUS, +5 V. Take a USB cable and horribly mangle it, to insert a 1-ohm resistor inline with the pin 1 conductor. Run your USB workload and measure voltage drop across the resistor with a DMM or similar. V = I * R and P = I * V, so with R = 1 the millivolts you read will be identical to the milliamps drawn by the device, and power will be five ...
