This probably requires some conversion.

This is a good thing, since if this is unique, people will be able to  
monitor multiple devices from the same host.

Most likely, the UPS reports this via a different variable and the  
driver defaults to on battery. Please post the output of

     /path/to/usbhid-ups -DD -a upsname

and we can have a look what needs to be done to add full support.

Thanks for that. Please not that as it is, the UPS devices that are  
already recognized by the liebert-hid subdriver have very limited  
support (they are lacking quite a number of essential features).  
Hopefully we will be able to add better support for this one.

We should probably make 0x10af the LIEBERT_VENDORID and add 0x0d6a as  
MEGAPOWER_VENDORID.
