find_all=True returns a list of devices (please see e.g. https://github.com/walac/pyusb/blob/master/docs/tutorial.rst) You must iterate through the list: devices = usb.core.find(find_all=True) for dev in devices: print (dev.idProduct, dev.idVendor) Probably you want to just find your device, and not all. It is all explained in the tutorial.
