Not clear udev behavior

[Atterratio]

When use steam like driver for controller, then udev events work normal. What I mean: if controller off and I start or close steam then "udevadm monitor" doesn't catch any event, if controller on and I start/close steam "udevadm monitor" catch events. If steam started and I turn on/off controler "udevadm monitor" catch events. But with this driver "udevadm monitor" catch events on "start/stop" driver daemon, not on power on/off controller.

Why it's important? I see in issues, that a man wrote a special daemon for checking the connection controller, to my opinion with the right behavior enough simple udev rules.

Sorry for bad english, I hope I was able to present the idea.
