Table 1. Automatic Port State to Port Indicator Color Mapping
The LED control lines can also be modulated with a square wave
for power conservation. The polarity of these pins is program-
mable, see on page 13.
In manual mode, the indicators are under the control of the host,
which can turn on the LEDs, or leave them off. This is done by a
USB Hub class request. Blinking of the LEDs is supported in
manual mode. The port indicators allow the user to intervene in
any error detection. For example, when babble is detected while
plugging in a defective device, or when an overcurrent condition
occurs, the port indicators corresponding to the downstream port
blink green or only light the amber LED, respectively.
