基本的に以下とほぼ同じ

• Debian GNU/Linux - nut - omron BY50FW
• Ubuntu 10.04 LTS - nut - omron BY50S

以下の環境で作業した。

# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 7.8 (wheezy)
Release:        7.8
Codename:       wheezy
# uname -a

# lsusb | grep "American Power Conversion"
Bus 002 Device 002: ID 051d:0002 American Power Conversion Uninterruptible Power Supply

以下の設定を、各ファイルに追記
/etc/nut/nut.conf

MODE=standalone

/etc/nut/ups.conf

[es500]
driver = usbhid-ups
port = auto

/etc/nut/upsd.conf

[upsmon]
password = xxxxxxxxxxxxxxxxxxxx
upsmon = master

/etc/nut/upsmon.conf

MONITOR es500@localhost 1 upsmon xxxxxxxxxxxxxxxxxxxx master

/lib/udev/rules.d/52-nut-usbups.rules を基に、ES 500 の idVendor, idProduct に合わせて、不要部分を削除して以下のファイルを作成。
/etc/udev/rules.d/52-nut-usbups-local.rules

ACTION!="add|change", GOTO="nut-usbups_rules_end"
SUBSYSTEM=="usb_device", GOTO="nut-usbups_rules_real"
SUBSYSTEM=="usb", GOTO="nut-usbups_rules_real"
BUS!="usb", GOTO="nut-usbups_rules_end"

LABEL="nut-usbups_rules_real"
# APC ES 500 - usbhid-ups
ATTR{idVendor}=="051d", ATTR{idProduct}=="0002", MODE="664", GROUP="nut"

LABEL="nut-usbups_rules_end"

以上で準備完了
次に udev で EX 500 に trigger かける

# udevadm control --reload-rules
# udevadm trigger --verbose --attr-match=idVendor=051d --attr-match=idProduct=0002
/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1

上記の結果より Bus, Device が 002, 002 なので以下の箇所を確認

# ls -l /dev/bus/usb/002/002
crw-rw-r-T 1 root nut 189, 129 Mar 18 17:49 /dev/bus/usb/002/002

上記のように mode が 664、user, group が root, nut になっていたら成功

usbhid-ups ドライバを直接起動してみる。

# /lib/nut/usbhid-ups -a es500 -DDD

failed が出なければ成功しているはずなので Ctrl-C で一旦止める。

あとは nut-server と nut-client を起動

# service nut-server start
Starting NUT - power devices information server and drivers:  driver(s). upsd.
# service nut-client start
Starting NUT - power device monitor and shutdown controller: nut-client.

最後に upsc コマンドで状態を確認
