Python OBD issues

I'm trying to get this cable to work but unfortunately impossible to use the OBD python library here is the error returned someone

would have any idea ?

or tell me if this cable is accountable? and if it is possible to do it from my pc.

Thank a lot

The code

import obd

connection = obd.OBD() # auto-connects to USB or RF port

cmd = obd.commands.SPEED # select an OBD command (sensor)

response = connection.query(cmd) # send the command, and parse the response

print(response.value) # returns unit-bearing values thanks to Pint
print(response.value.to("mph")) # user-friendly unit conversions

The error:

That’s a counterfeit VAG-COM cable, the library is built for ELM327 command set cables.
