What do the red & green LEDs mean?

The nCube hub has a green LED and a red LED.

The red LED shows the device is powered up and working.

The green LED shows it is active and will flicker from time to time.

If the red LED flickers off regularly then the hub is not getting enough power.  Although the hub is powered by a micro-USB port as per a lot of mobile phones, not every mobile phone charger, or USB hub, provides enough power for the nCube hub so you must use the power supply and the USB lead supplied with nCube as we specified and tested these to be capable of powering nCube.
