The mouse works perfectly with my brothers pc (also a laptop), so i tried updating the mouse from there with razer synapse. It is stuck at the screen that says: 'please connect a razer synapse 2.0 enabled device'.

It doesn't light up, nor does it move or click. I just bought my new Razer Naga 2014 yesterday and to my surprise it didn't work. I have the excact same problem!! This is a description of mine:
