This isn't a device that is supported by usbhid-ups. However, we have  
seen the bogus VID:PID combination before. You might want to give the  
blazer_usb or megatec_usb drivers a try. If you're lucky, these might  
give you limited support to at least monitor the status of the UPS.

Note that neither driver will support the shutdown function. If you're  
willing to decode how that works for this UPS (if possible at all),  
you'll probably have to snoop the communication between Windows driver  
and the UPS.
