I am trying to catch devtype=usb_interface and pass devname of the usb_device it came from, kinda like this: ACTION=="add" ENV{DEVTYPE}=="usb_interface" RUN+="/path/to/exec/exec_41_udevrules.py '%E{ACTION}' '%E{DEVNAME}'" problem is passing DEVNAME like this doesn't work, it passes as empty variable.

Here is the output of sudo udevadm monitor --udev --subsystem-match=usb --property when I plug an usb modem: https://termbin.com/m458

So in this example, I'd like to pass /dev/bus/usb/002/111 (devname) at every devtype usb_interface add event

Perhaps it is `%N`? – Ian Abbott Aug 19 '20 at 15:12
@lan Abbott I'll give it a try a bit later and post an update – John Doe Aug 19 '20 at 17:13
