On Windows 10, modifying a file the pyrplidar_serial.py from library helps. In line 13 replace: "self._serial = serial.Serial(port, baudrate, parity=serial.PARITY_NONE, stopbits=serial.STOPBITS_ONE, timeout=timeout, dsrdtr=True)" to " self._serial = serial.Serial(port, baudrate, parity=serial.PARITY_NONE, stopbits=serial.STOPBITS_ONE, timeout=timeout, dsrdtr=False)"
