@andreamaglione have you installed the edgetpu runtime.

If yes, please add the below lines at import section in your test script and share the logs:

from pycoral.pybind._pywrap_coral import SetVerbosity as set_verbosity
set_verbosity(10)

@hjonnala I have the same issue, and already tried your suggestion here without any luck. I added the lines to the example classify_image.py and got this output:

Errors went away after I ran the examples on Linux bare metal. I guess it was trying to update the firmware of the Coral through the Windows VM, and that caused USB hotplugging issues. Running it bare metal on Linux must have updated the firmware. Now works over Windows VM (at least until the next firmware update...).
