Comment 68 for bug 969489

In my computer, bumblebee started causing this problem.

A suggested fix, given in https://github.com/Bumblebee-Project/Bumblebee/issues/205#issuecomment-8022153 did not solve the problem, and added a delay. However the "and stopped udevtrigger" seems to be working with a fresh bumblebee install (so, without delay).

One thing that may be interesting is that the problem did not happen when I had the phones plugged in.
