I got this link and its working fine [ http://packages.python.org/pyudev/api/monitor.html ] >>> context = pyudev.Context() >>> monitor = pyudev.Monitor.from_netlink(context) >>> monitor.filter_by(subsystem='input') >>> for action, device in monitor: ... print('{0}: {1}'.format(action, device)) but when I am trying to execute code [ http://packages.python.org/pyudev/api/toolkit.html ] import pyudev, sys context = pyudev.Context() monitor = pyudev.Monitor.from_netlink(context) monitor.filter_by(subsystem='usb') observer = QUDevMonitorObserver(monitor) def device_connected(device): print('{0!r} added'.format(device)) observer.deviceAdded.connect(device_connected) monitor.start() I am getting Traceback (most recent call last): File "Mount.py", line 7, in <module> observer = QUDevMonitorObserver(monitor) NameError: name 'QUDevMonitorObserver' is not defined Could any one please tell me how to avoid this error .
