Bug#457616: udev no longer passes USB device remove events

[Anthony L. Awtrey]

This patch fixed my problem, but it's probably a wrong approach. It
looks like udev tries to blindly remove device nodes for any remove
event. Since raw USB devices don't have device nodes, all "remove usb"
events fail.
