Hi.

I am using Debian Lenny, w. kernel 2.26-2-686-bigmem.
I have a MGE UPS ProtectionCenter 675. It works under Windows XP, and
physically works.

It has a USB which is linked with this computer. The first problem is:

# lsusb
Bus 008 Device 002: ID 152d:2336 JMicron Technology Corp. / JMicron USA Technology Corp.
Bus 008 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 003: ID 03f0:3304 Hewlett-Packard DeskJet 990c
Bus 002 Device 002: ID 046d:c03e Logitech, Inc. Premium Optical Wheel Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

There is actually no recognized UPS, even if

# dmesg | grep hid
[ 4.769903] usbcore: registered new interface driver hiddev
[ 4.909003] input,hidraw0: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:1a.1-1
[ 4.909018] usbcore: registered new interface driver usbhid
[ 4.909020] usbhid: v2.6:USB HID core driver

HID is thus ok, even if I should have hid extensions for my UPS in
this list.

I then
# mknod /dev/usb/hiddev0 c 180 96

Then,

# apt-get install nut nut-usb mgeups-psp

Everything is fine, even if nut-usb is a virtual package, apparently
provided by nut, AFAIK.

I then edit /etc/default/nut, putting
==
# start upsd
START_UPSD=yes

# start upsmon
START_UPSMON=yes
==
(I am on the `master' computer, for the UPS.)

I then write in /etc/nut/ups.conf:
==
# define the ups driver and the port where it's connected
[myups]
driver=hidups
port=/dev/usb/hiddev0
==


I then create the network config (in /etc/nut/upsd.conf):
==
# access-lists:
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACL lan 192.168.1.0/24

# rights:
ACCEPT localhost lan
REJECT all
==
(justified as my upsd is 2.2.2.)

I then edit /etc/nut/upsd.users:

==
# define the user rights according to the ACL in upsd.conf
[user]
password = mypassword
allowfrom = localhost lan
upsmon master
==

After that, I evidently edit /etc/nut/upsmon.conf:

==
# define the ups to monitor and the permissions
MONITOR myups(a)localhost 1 nutuser mypassword master

# define the shutdown comand
SHUTDOWNCMD "/sbin/shutdown -h now"
==

I finally create a `nutuser' user, in the `nut' group.

I then have:

# /etc/init.d/nut start
Starting Network UPS Tools: (upsdrvctl failed).

Okay. The output of
# dmesg | grep hid
is still the same.

I then notice that
# cat ups.conf
# define the ups driver and the port where it is connected
[myups]
driver=hidups
port=/dev/usb/hiddev0

seems to use a not-known driver, as `hidups' seems to be disliked:
# upsdrvctl start
Network UPS Tools - UPS driver controller 2.2.2
Can't start /lib/nut/hidups: No such file or directory

I then modify ups.conf, changing the `driver' to `newhidups'. It then
results in
# upsdrvctl start
Network UPS Tools - UPS driver controller 2.2.2
Can't start /lib/nut/newhidups: No such file or directory

I then try some advice I found on a russian forum, /i.e./ adding
`user=nutuser' at the end of ups.conf. I then try with the three
different drivers. Still same problem.

After a
/lib/nut# ls -al
I then realize that usbhid-ups could be a potential driver (the two
other being not listed here: why?). I then try to write
==
# define the ups driver and the port where it is connected
[myups]
driver=usbhid-ups
port=/dev/usb/hiddev0
==
with or without the `user' field. Seems to be better:
# upsdrvctl start
Network UPS Tools - UPS driver controller 2.2.2
Network UPS Tools: 0.29 USB communication driver - core 0.33 (2.2.2)

No matching HID UPS found

But still no UPS found.

I then try

You can see that there is no problem there.

I occasionnaly receive
==
Broadcast Message from nut(a)merciadriluca-station
(somewhere) at 16:21 ...

UPS myups(a)localhost is unavailable
==

This can be understood easily, as
# cat /var/log/syslog
and
# cat /var/log/daemon.log

give me

[...]

The best result I had was

Dec 25 16:16:46 merciadriluca-station upsd[4624]: Client nutuser(a)127.0.0.1 logged into UPS [myups]

However, I always had
# upsc myups(a)localhost
Error: Driver not connected


Is there somebody out here who would be able to get me out of these
problems? My idea is that the problem comes from the `driver' and its
corresponding value.

Thanks folks.
