Help with matching a HID device (udev rules troubles)

[Richard Hughes]

I'm trying to fix UPS support in DeviceKit-power. It's basically all
down to incorrect udev rules. The device I'm trying to match is the
last one in the chain, i.e. the one with DEVNAME=/dev/usb/hiddev0 :

It's easy to match all devices with something like SUBSYSTEM=="usb",
ATTRS{idVendor}=="0463", ATTRS{idProduct}=="ffff", but then this
matches all devices, and I only want the hiddev0 device, not the
hidraw1 device. Ideas welcome. Thanks.

Richard.
