No. The module that we call through udev is for runtime-pm. And that too is triggered when we have the add or remove event generated, which typically happens when you plug/unplug a USB device. What does your dmesg look like ? does the kernel complain of any flaky USB hub ? > > I'm not sure why so many udev events are spawned on boot.

I'll get back to you shortly with the results. That rule is important to LMT. LMT is triggered on kernel events. If that rule is not present, you won't be able to act when some events are triggered in the kernel, for hotplug devices. -- Ritesh Raj Sarraf RESEARCHUT - http://www.researchut.com "Necessity is the mother of invention."
