What steps will reproduce the problem?
1. Use code from Inquiry.py example
2. returns line 89, in handleBroadcast
    nearby_devices = bluetooth.discover_devices(lookup_names = True)
  File "C:\Python27\lib\site-packages\bluetooth\msbt.py", line 9, in discover_devices
    return bt.discover_devices (flush_cache, lookup_names, lookup_class)

The expected output is that the bluetooth adapter is found. It is included on 
the Microsoft bluetooth stack (At hardware>devices it says Microsoft Bluetooth 
Enumerator)

Is this the only BT device on list in device manager?
Can You list nearby BT devices from Windows 8.1 gui?
After You list BT devices from windows GUI, is there still problem with 
Inquiry.py example?

I just reproduced this issue, but after listing nearby BT devices from windows 
gui everything started to work.
So it looks like some kind of WP8.1 feature/bug
Anyway I will try to find some solution
