smdev: Manually set permissions on bus/usb nodes
I couldn't figure out how to get smdev to set the owner/permissions
on nodes that get created in bus/usb/[0-9]+/[0-9]+. It's possible
it doesn't support this, even though mdev has this sort of regex
matching with folder depth, e.g.:
$DEVNAME=bus/usb/([0-9]+)/([0-9]+) root:plugdev 0660 =bus/usb/%1/%2
Instead I've put in a terrible hack to just run a command on these
nodes when they appear and set permissions with chmod/chgrp.
