Eaton is now the owner of what was formerly known as MGE Office  
Protection Systems, which in turn is part of what used to be known as

There is. See 'man 8 usbhid-ups' for all regular expressions that you  
can use to identify units.

The value of port isn't used, so we recommend setting it to

          port = auto

to prevent people from thinking that it attaches to the location  
specified (this value needs to be present, but isn't actually used).

The driver reads most parameters directly from ups.conf, so this isn't  
added by upsdrvctl.

This isn't needed. Running

     /lib/nut/usbhid-ups -DD -a ups1


     /lib/nut/usbhid-ups -DD -a ups2

in another window should result in both instances running fine.  
Likewise, running it from upsdrvctl (with the above ups.conf file)  
should also work. Please confirm that there are no instances of  
usbhid-ups left running in the background before trying this out. This  
is a common mistake.

One thing you may want to check as well, is that there are no trailing  
spaces in ups.conf. We have unconfirmed reports that this could  
confuse the configuration parser (but were never able to reproduce the
