Minor nit, but for anyone else using an exact match search interface (like packages.ubuntu.com), note that there is a "d" after "hal": hald-addon-hid-ups

What if you convert the USB ID numbers to decimal?

        <match key="@info.parent:usb.vendor_id" int="2748">
          <match key="@info.parent:usb.product_id" int="12310">

This sounds a lot like what this file was designed to do:

  https://github.com/networkupstools/nut/blob/master/scripts/upower/95-upower-hid.rules

(It is auto-generated from all of the NUT drivers at release time.)

Is this CentOS? Which version?
