I have an orange pi and I have installed python-obd library, it throws an exception when I try to connect or even when I try to scan the ports, apparently it comes from the pyserial library (version 3.4), this is the error it gives:
import obd
ports = obd.scan_serial()
Traceback (most recent call last):

BrokenPipeError: [Errno 32] Broken pipe
Same error ocurrs with python2.7 and python3. Any idea what might be happening?
