Failure to start due to assertion error

Using a Go Control stick (Silicon Labs chip), been running with Home Assistant just fine. Run into the following:

root@f2e832ada290:/# python3 hue-thief/hue-thief.py /dev/ttyUSB1 
Exception in callback SerialTransport._read_ready()
handle: <Handle SerialTransport._read_ready()>
Traceback (most recent call last):

  File "/usr/local/lib/python3.9/site-packages/bellows/ezsp.py", line 169, in frame_received
    assert expected_id == frame_id
AssertionError

Not sure if this is a bellows issue or how hue-thief is trying to use it. Any pointers appreciated!

I'm seeing exactly the same thing with Python 3.8.10 on Ubuntu with a Nortek HUSBZB-1.

$ python3 hue-thief.py /dev/ttyUSB1

If you're running into this, another app is most likely still use your ZigBee dongle.

For me, the solution was to just use a separate RaspPi. however, there are less extreme versions.

Disabling the dongle in Home Assistant may help? 🤔

Or a second solution would be to boot your Home Assistant hub from another hard drive and just boot it on RaspbianOS temporarily would work for sure. But this requires a secondary boot drive.
