Unfortunately, this won't be able to be supported by the usbhid-ups driver - it looks like they are using USB HID to emulate a serial port. (A true USB HID Power Device Class report descriptor is generally several hundred bytes long, versus the 37 shown here).

Is it possible that you just need to load the usbserial kernel module, and bind it to the UPS' 0d9f:0002 ID? Then the /dev/ttyUSB* port can be passed to the "powercom" driver. (This is suggested by http://networkupstools.org/stable-hcl.html?manufacturer=Powercom&connection=USB )
