"""Utility to diagnose Bumble SoundDeviceAudioInput compatibility.

Run inside the project venv:
    python -m tests.usb_audio_diag [rate]
It enumerates all PortAudio input devices and tries to open each with Bumble's
create_audio_input using the URI pattern `device:<index>` with an explicit input_format of `int16le,<rate>,1`.
