Try running 'udevadm monitor' as root and see if something shows up
there.

I can't reproduce this here, running a newer version of udev (195),
sorry, I don't have any systems with older udev releases.

Note, someone else posted this same error earlier today on the linux-usb
mailing list, saying that USB storage devices would not automount
anymore. Does that work properly for you?
