I am trying to configure NUT to work with a new CyberPower CP1500C UPS via a USB connection. As far as I can tell everything is configured correctly -- the system recognizes the UPS and can talk to it, and when I start upsd everything is fine at first. Unfortunately, a few seconds after upsd starts, my syslog is flooded with time out errors every 2 seconds.
Here is what happens after I start upsd:
Code:
[root@localhost /]# service upsd start
NUT Starting UPS model drivers: Network UPS Tools - UPS driver controller 2.4.3
Network UPS Tools - Generic HID driver 0.34 (2.4.3)

So far so good. However, almost immediately my syslog will fill up with this:
Code:
[root@localhost log]# more syslog

[root@localhost log]#
This will continue until I stop the upsd service. During this time, upsmon appears to find and connect to the UPS just fine:
Code:
[root@localhost log]# more syslog
Aug 7 01:46:24 localhost usbhid-ups[6401]: libusb_get_report: Connection timed out
Aug 7 01:46:24 localhost upsmon[6610]: Startup successful

Aug 7 01:46:26 localhost usbhid-ups[6401]: libusb_get_report: Connection timed out
[root@localhost log]#
I can't figure out what the problem is. At first I thought the problem might be something else trying to steal control of the UPS, but I don't know how to tell if that's happening. My setup seems pretty straightforward and I'm not trying to do anything weird or fancy. Here's the output from lsusb:
Code:

Here's my configuration in upsd.conf:
Code:
[ups_main]
driver = usbhid-ups
port = auto
desc = "Main Server UPS"
I am running Mandriva 2010.1 and my kernel is 2.6.33.5-desktop-2mnb. Any help would be much appreciated. I would even be happy if someone could simply tell me how to stop logging the continuous errors since the upsmon service appears to talk to the UPS just fine. Thanks!
