Looks like the hid driver isn't loaded (like Greg said),
but I don't think that loading it will solve the problem
because it looks like the hid driver doesn't support the
Power Device spec HID usage pages.
In general we don't have support for USB UPS (Power) devices
AFAIK. APCC was at the USB PlugFest and at LinuxWorld
last week and they are very interested in making sure that
we do power device support correctly and are willing to
discuss it with us.
Also, what application(s) were you planning to use to talk
to the device, once a device driver will talk to it?
