Well, the only thing I can say, is, that I use libusbx under the hood. I've found a pretty clean solution for my problem.
I just call once usb.core.find(find_all=True) every 2 second and look up first for the usb hub und reuse the retrieved list, to find the usb devices connected to the hub. In the past I called find() two times per intervall in a very short time and when I called it the second time, an exception rose after approximately 15 intervalls.
