/etc/xensource/usb-policy.conf is owned by the RPM manager. A customer who edits it to allow/deny some USB devices loses their changes on the next RPM uprade. usb_scan.py now also reads any *.conf files found in /etc/xensource/usb-policy.conf.d, in alphabetical order before it reads the main policy file. Since the first match wins the user rule always override the main file rule. If the drop-in dir doesn't exist, behaviour is unchanged.
