nut-scanner does not suggest a "device" matching setting for USB #1790
Description
As posted in #1414, "duplicate" device support is problematic because not all data fields useful for device matching are proposed for driver configuration. For example, a box which monitored two devices in that issue could not discern between them with the data provided (while the unique device=... values would have helped):
:; nut-scanner -U
Scanning USB bus.
