thanks for the clarification. But I’m wondering: Is it correct that for both devices, the same file in /dev is created resp. reused? $ udevadm test /sys/bus/usb/devices/2-2/usb_device/usbdev2.2/ 2>&1 | fgrep NAME udev_rules_apply_to_event: NAME 'bus/usb/002/002' /lib/udev/rules.d/50-udev.rules:39 $ udevadm test /sys/bus/usb/devices/2-2 2>&1 | fgrep NAME udev_rules_apply_to_event: NAME 'bus/usb/002/002' /lib/udev/rules.d/50-udev.rules:35 I’d expect that only one level of the USB protocol should get this NAME.
