usb devices and devfs settings

When I add usb devices after booting the system, the associated devices
do show up in devfs. In my case: da0 and das0.

However, the permissions on these devices does not change, despite
devfs.conf.

So how about adding the following to devd.conf in the default system:

Note: the sleep 1 is necessary to give geom the chance to come up
with devices before devd start executing /etc/rc.d/devfs
