Serial numbers are not unique across devices.

[cmacfarl]

The pixy2 device always reports "DEMO 0.0" as its serial number.

It would be nice for the device to be able to either have unique serial numbers from the manufacturer, and/or have the ability through pixymon to set a device's serial number.
