Hi, I had a brief discussion with John on this matter and was being told that the reason for this filter was to optimize boot time.
When we remove the /dev filter, boot time will increase considerably on lower end devices due to the resulting hotplug-call overhead of the huge volume of additional uevents. A better approach here would be to selectively whitelist uevents based on subsystem or similar attributes, e.g. `DEVTYPE=usb_device`. ~ Jo
