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

My /usr/local/etc/nut/ups.conf reads:
[eaton]
driver=blazer_usb
port=/dev/ugen5.2
The error occurs at unpredictable time intervals.
It happens even when driver runs as root so I think permissions are not
involved here.
Thanks in advance for your advices.

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