Thanks for the quick reply!
No I haven't installed any drivers. I just tried to build the one you linked to but it fails.
Ubuntu 13.04 uses the 3.8.0-22 kernel which as far as I know already has the driver built in. /dev/ttyUSB0 appears so I guess this implies it does. Here's my syslog when i plug the device in :

When I try and communicate directly with "screen /dev/ttyUSB0 115200" I get not output. Never tried this before so not sure if that means anything.
I would like to get this running on Linux (eventually my Raspberry Pi) and I don't have Windows so I'm unable to try any Windows programs / guides.
