<br>
All I can recommend is add a delay into how often the UPS is
polled.<br>
<br>
To this by inserting <i>pollinterval =10</i> into the ups.conf
file and see how you go.<br>
<br>
For me this just prolonged the time until it failed but others
have had success with this driver and the delay.<br>

I ran into exactly the same problem as described.
<br>
OS: FreeBSD 9.0-Rel
<br>
UPS: Eaton E-Series NV 600H
<br>
NUT: from Ports, nut-2.6.5_1
<br>
driver: blazer_usb
<br>
<br>
I am sure the problem is not permission-related as it occurs even
when the driver runs as root.
<br>
My tested recipe for USB permissions is:
<br>
<br>
1. run usbconfig to find where the device is connected. In my
case:
<br>
ugen5.2: <USB to Serial INNO TECH> at usbus5, cfg=0 md=HOST
spd=LOW (1.5Mbps) pwr=ON
<br>
<br>
2. edit /etc/devfs.rules and add:
<br>
[nut_usb=10]
<br>
add path 'ugen5.2' group wheel user uucp mode 0770
<br>
<br>
3. edit /etc/devfs.conf and add:
<br>
perm ugen5.2 0770
<br>
own ugen5.2 uucp:wheel
<br>
<br>
4. Edit /etc/rc.conf and add:
<br>
devfs_system_ruleset="nut_usb"
<br>
<br>
5. Now it's necessary to restart devfs (or the whole system if you
prefer):
<br>
/etc/rc.d/devfs restart
<br>
<br>
So ls -l /dev/ug* shows:
<br>
lrwxrwx--- 1 uucp wheel 9 Dec 24 23:36 /dev/ugen5.2 ->
usb/5.2.0
<br>
and ls -l /dev/usb shows:
<br>
crwxrwx--- 1 uucp wheel 0, 147 Dec 24 23:36 5.2.0
<br>
<br>
So I tried to debug but strange:
<br>
export USB_DEBUG=3
<br>
does not have effect on the output from blazer_usb.
<br>
Here are few results:
<br>
<br>
# /usr/local/libexec/nut/blazer_usb -DDDD -a eaton -u uucp

My /usr/local/etc/nut/ups.conf reads:

The error occurs at unpredictable time intervals.
<br>
It happens even when driver runs as root so I think permissions
are not involved here.

Thanks in advance for your advices.
