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 enable the user to intervene
in any error detection. For example, when babble is detected
while plugging in a defective device, or when an overcurrent

downstream port blink green or only light the amber LED,
respectively.
