[Nut-upsuser] Sucess with Powerware 5115A over USB!

[Daniel Burr]

THE GOOD:

NUT is able to communicate with my Powerware 5115A over USB using the
bcmxcp_usb driver:

ambient.temperature: 38
battery.charge: 99
battery.runtime: 9000
battery.voltage: 27.07
driver.name: bcmxcp_usb
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.version: 2.2.1
driver.version.internal: 0.13
input.frequency: 50.34
input.voltage: 235
output.current:  0.0
output.frequency: 50.34
output.phases: 1
output.voltage: 235
output.voltage.nominal: 240
ups.firmware: Cont:01.00 Inve:10.05
ups.load:   0.0
ups.model: 51151000A           1000VA
ups.power.nominal: 1000
ups.serial: UZ117A0044
ups.status: OL


THE BAD:

Powerware 5115A support is not included in the latest release (2.2.1).
When I try to run `/lib/nut/bcmxcp_usb -a powerware` with the latest
debian package installed I see the following error message which has
previously been reported on the mailing list in October 2005 and June
2007:

Communications with UPS lost: Receive error (Request command): COMMAND:
31

RECONNECT USB DEVICE

Communications with UPS lost: Receive error (Request command): COMMAND:

RECONNECT USB DEVICE

Communications with UPS lost: Error executing command
Could not communicate with the ups: Inappropriate ioctl for device


THE UGLY:

It is possible to create a deb with patched in support for the Powerware
5115A using the following steps:

1. sudo apt-get source nut
2. sudo apt-get build-dep nut
3. wget
'http://svn.debian.org/wsvn/nut/trunk/drivers/nut_usb.c?op=file&rev=1220&sc=1' -O nut_usb.c.new
4. wget
'http://boxster.ghz.cc/projects/nut/browser/trunk/scripts/udev/nut-usbups.rules.in?format=raw' -O nut-usbups.rules.in.new
5. wget
'http://svn.debian.org/wsvn/nut/trunk/drivers/nut_usb.h?op=file&rev=1220&sc=1' -O nut_usb.h.new
6. mkdir nut-2.2.1/debian/patches
7. diff -ruN nut-2.2.1/drivers/nut_usb.c nut_usb.c.new | dpatch
patch-template -p > nut-2.2.1/debian/patches/01-nut_usb.c
8. diff -ruN nut-2.2.1/drivers/nut_usb.h nut_usb.h.new | dpatch
patch-template -p > nut-2.2.1/debian/patches/03-nut_usb.h
9. diff -ruN nut-2.2.1/scripts/udev/nut-usbups.rules.in
nut-usbups.rules.in.new | dpatch patch-template -p >
nut-2.2.1/debian/patches/02-nut-usbups.rules.in
10. cd nut-2.2.1/
11. echo -e '01-nut_usb.c\n02-nut-usbups.rules.in\n03-nut_usb.h' >
debian/patches/00list
12. sudo dpkg-buildpackage -tc
13. sudo dpkg -i ../nut_2.2.1-2_i386.deb


Thanks for all your hard work!
