Public bug reported:

My OS Ubuntu 25.04 finds a single Bluetooth Adapter hci1, which is
correct according to computer specs.

However, when I use Python 3.13.3 with Bluetooth module 'simplepyble
0.10.3' I get this adapter, plus an extra one named 'test':

BTsetup:            Found 2 Bluetooth Adapters
   #1  Name: hci1   MAC-Addr: DC:97:BA:3F:D9:5E
   #2  Name: test
      EXCEPTION: BTsetup:             >'Path /org/bluez/test does not contain 
interface org.bluez.Adapter1'<  in file: gdev_DMM.py in line: 262

Unsurprisingly, this 'test' thing does not have any Bluetooth properties
except for the name (reported as adapter.identifier())

Using the proper hci1 adapter, all the devices are found correctly.

I checked with the simplepyble authors, and they say it can not result from it:
