So that we don't retry to open it every 2 seconds flooding stderr with error messages.
The polling here is done intentionally, so the devices catched by the filter show up in the guest automagically as soon as they are plugged in. Just zapping the filter on failure isn't the right thing to do here.
We could try to do something more clever than polling sysfs every two seconds though, such using inotify to watch /sys/bus/usb/devices for new devices poping up.
cheers, Gerd
