кто разбирался с dbus-python, пожалуйста, подскажите как определить куда автоматически примаунтился usb-disc
есть обработка подключения нового устройства через
bus = dbus.SystemBus() bus.add_signal_receiver(def_device_add, 'DeviceAdded', 'org.freedesktop.Hal.Manager', 'org.freedesktop.Hal', '/org/freedesktop/Hal/Manager')
в def_device_add проверяем аргументы на содержание “volume” и смотрим /mnt и д.р. папки или /etc/mtab
при этом на NewCapability тоже прописана функция, но почему-то она не выполняется
нашел код почти решающий задачу, но он при запуске ругается
hal_service = bus.get_service('org.freedesktop.Hal')
AttributeError: ‘SystemBus’ object has no attribute ‘get_service’
