[Nut-upsuser] usbhid-ups works, upsc doesn't - help?

[Dave]

Hi, Folks,

I'm new to this admin game, and one of the hardest parts for me is  
figuring out where files/programs/data are stored in the file system.  
I think this is one of these situations.

I've installed NUT on my Mac OS X 10.5 server, using the macports  
build. The machine is a dual processor G4 tower, connected to an APC  
UPS via USB.

usbhid-ups seems to be working, see output below. However, when I run
  /opt/local/bin/upsc apcups at localhost
All I get is an error message: Error: Data stale

When I run upslog, it seems to clearly not be finding the data that  
usbhid-ups is getting:

$ sudo  /opt/local/bin/upslog -s apcups -l-
Network UPS Tools upslog 2.2.2
logging status of apcups to - (30s intervals)
20081016 103242 NA NA NA [NA] NA NA

So, my questions is this: Where does the status data get stored? It is  
being polled regularly once I run "sudo /opt/local/bin/upsdrvctl  
start", but then it can't be found.

Does anyone have any idea about this? I'm been looking into this very  
carefully, but I'm at a wall here.

Thanks!

Dave

Data/Details below:


  My ups.conf looks like this:

[apcups]
         driver = usbhid-ups
         port = auto

My upsd.conf looks like this:

ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32

ACCEPT localhost
REJECT all

When I run:
  sudo /opt/local/bin/usbhid-ups -a apcups -DD
I get what looks to be success:
