There is a blue led for each of the downstream USB ports on the hub. The LEDs turn on when a USB device is connected and recognized by the operating system. These lights may turn off even though a device is connected when the host computer operating system puts the device to sleep to conserve power. There is no master light to indicate the hub is receiving power.
