for me too, with and without using the uhub. thanks!
there are two console logs at the end of my message, first one is just
to show your code at work and that it is working.
second one is the console log when running usbdevs via hotplugd
instantly after attaching pcmcia uhub (kernel panic). since I have no
idea whether that is related I seek your advice on what to do with this.
look for "Session" and "note: "

everything is fine.
