[Nut-upsuser] Tripplite OMNIVIS1500XL Connection Refused

[Dave Wortman]

I'm having problems creating a UPS connection to my Tripp Lite UPS

System:  Ubuntu 8.04.2    Nut 2.4.1  freshly compiled from source.

When I do      upsdrvctl start     everything appears to work and I get
      :Detected a UPS: TRIPP LITE/TRIPP LITE UPS
      Using OMNIVS 2001 protocol (2001)
      Unit ID not retrieved (not available on all models)
      Attached to Tripp Lite UPS

But when I try to start upsd and upsmon I get

May  6 15:34:03 <my host>  upsd[8834]: listening on 127.0.0.1 port 3493
May  6 15:34:03 <my host>  upsd[8834]: Can't connect to UPS [ups]
(tripplite_usb-ups): Connection refused
May  6 15:34:03 <my host>  upsd[8835]: Startup successful
May  6 15:34:03 <my host>  upsmon[8837]: Startup successful
May  6 15:34:03 <my host>  upsd[8835]: User nut at 127.0.0.1 logged into UPS
[ups]
May  6 15:34:03 <my host>  upsmon[8838]: Poll UPS [ups at localhost] failed -
Driver not connected
May  6 15:34:03 <my host>  upsmon[8838]: Communications with UPS
ups at localhost lost

The permissions on the usb devices seem OK

/dev/bus/usb/001
crw-rw-r-- 1 root root 189, 0 2009-05-06 14:48 001
crw-rw-r-- 1 root nut  189, 2 2009-05-06 15:33 003

usp.conf is very simple

[ups]
    driver = tripplite_usb
    port = auto
    desc = "Tripplite OMNIVS1500XL"

and upsd.con contains only

LISTEN 127.0.0.1 3493
MAXCONN 128

Suggestions?
