Comment 4 for bug 1497

OK. So I've been investigating a bit. The apropriate udev scripts are present in /etc/udev/rules.d/45-libnjb.rules.

These correctly set the permissions on /dev/bus/usb/00x/00y to root:plugdev and 0660 and my user is in the group plugdev. I can't seem to repeat the problem after having used the old hotplug scripts, even though I have removed them now. But the first time I plugged the zen in, it gave this error message.
