My first moonlander 2 just turned up ! 
all working. This is a picture of my setup:

Consists of:
1) Raspberry PI 3 with official Rapsberry PI 3 power supply
2) Cheap USB 2.0 7 port hub - Pluscom Model u7PH-3A (not using the power supply as the Pi seems to be enough for this) cascaded into:
3) Plugable USB 3.0 7 port Hub (inc 12V 5A 60w psu) - Model: USB3-HUB7BC
3 more are in the post in the way so will be testing more plugged into the same when i can (going to try and do 7x all at the time time via extension cables)
Been running now for about an hour now litecoinpool reporting hashing at 3,498kH/s (so far so good!)
Boom!
