Enumeration DeviceFamily

Enumeration representing the device family.

The family is an umbrella axis grouping devices by their host generation (and other non-USB families). It carries the canonical generation, unlike DeviceInterfaceType which is named by transport:

• USB Gen 1 = FX2 based
• USB Gen 2 = FX3 based
• USB Gen 3 = FX5/FX10/FX20 family
• PCIe Gen 1 = PCIe based (e.g. XEM6110)
