[Nut-upsdev] usbhid-ups driver

[Matt Dunnington]

I've just upgraded NUT from 2.0.2 to 2.2.0 and have read the upgrading 
file, which led me to submitting this message. I have changed nut.conf 
to use 'driver = usbhid-ups' and 'productid = ffff', but I still get 'No 
matching HID UPS found' when I try to start the driver. The UPS (a 
Liebert PowerSure Personal XT 450VA) was working fine with 2.0.2 and the 
hidups driver. Is there a workaround for this with 2.2.0?
