Power Idle: 2mA (0.0066W @ 3.3Vdc) (0.01W @ 5Vdc)
Connected: 7mA (0.0231W @ 3.3Vdc) (0.035W @ 5Vdc)
Fast Data: 45mA (0.1485W @ 3.3Vdc) (0.225W @ 5Vdc)
Inquiry: 70mA (0.231W @ 3.3Vdc) (0.35W @ 5Vdc)
Notes: These power measurements were taken with no LEDs connected.
Driving an LED through 330 ohm resistor to GND draws an additional
4mA on 5V for each LED.
