Hi Arjen and all,
I succeeded in having a controlled shutdown, when the UPS went in
low-battery status.
I'm happy with the result.
However, I've just realized that I had also done another change in the
drivers' source code: I changed the belkin-hid.c and liebert-hid.c
drivers, in order to select the liebert driver, instead of the belkin
one, when my vendor ID was found.
Without this change, I'm not able to correctly see the online/on
battery status (I always see "on battery"), even with the suggested
change in libhid.c.
In detail, my change is the following:

Yes!
The results are quite different now :)
This is the result of "upsc" now, when AC power is plugged in:
battery.charge: 100
battery.type: PbAc
battery.voltage: 28
battery.voltage.nominal: 2
device.mfr: Emerson Network Power
device.model: LiebertPSA
device.serial:
device.type: ups
driver.name: usbhid-ups
driver.parameter.pollfreq: 30
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.version: 2.6.0
driver.version.data: Liebert HID 0.3
driver.version.internal: 0.35
ups.mfr: Emerson Network Power
ups.model: LiebertPSA
ups.productid: 0001
ups.serial:
ups.status: OL CHRG
ups.vendorid: 10af
And, if I unplug the AC power, the following parameter changes:
ups.status: OB DISCHRG
Thank you Arjen: you gave me a good support, in a very short time.
I'm ready now to go on with NUT configuration: I think I'm able now to
have a controlled PC shutdown.
I'll let you know how it goes.

Re: [Nut-upsuser] Status OB (on battery) when polling a Liebert PSA
Citeren Pier Paolo Glave :
Please find attached the log of "/lib/nut/usbhid-ups -D -a liebert",
produced with the 2.6 driver.
From this it is quite clear what is happening. The UPS *is* reporting
the values needed, but the people that wrote the firmware of this
device apparently got some things horribly wrong in the report
descriptor. For many variables, the exponents are incorrect. It is
nonsense to report the status bits (like
UPS.PowerSummary.PresentStatus.*) with the unit "V" (00f0d121). This
means that instead of integer values (0 or 1), these values are
reported as floating point (0 or 1e-07) due to the exponent that is
embedded in the unit. Subsequent parsing of the values fails.
It looks like the firmware developers missed the fact that for some
units, an exponent is used (V, VA and W) which causes a 7 decades
offset. You either have to account for that in the units exponent or
use a type that doesn't have this offset. I'm fairly certain that by
commenting out the following lines in drivers/libhid.c
604 for (i = 0; i < NB_HID_UNITS; i++) {
605
606 if (HIDUnits[i].Type == hiddata->Unit) {
607 unit_expo -= HIDUnits[i].Expo;
608 break;
609 }
610 }
you'll get better results. Please let us know if it does, so that we
can include this fix in the belkin-hid subdriver.
Best regards, Arjen

[Nut-upsuser] Status OB (on battery) when polling a Liebert PSA
Hi all, This is my first experience with NUT. I'm trying to test a Liebert PSA 1500 UPS, connected via USB to a single PC. I have followed the instruction in the "Configuration" section of the online user manual. Everything seems to be fine, except that, when I run "upsc liebert@localhostups.status", it retuns "OB", even if the UPS is currently online. Here are the information related to my system: - Debian 6.0 on Intel Pentium 4; kernel version 2.6.32-5-686; - NUT version 2.4.3-1.1squeeze1, installed with package system; - UPS: Liebert PSA1500MT3-230U My ups.conf is the following: [liebert] driver = usbhid-ups port = auto desc = "Liebert PSA1500MT3 UPS" The result of "upsdrvctl start" is: Network UPS Tools - UPS driver controller 2.4.3 Network UPS Tools - Generic HID driver 0.34 (2.4.3) USB communication driver 0.31 Using subdriver: Belkin HID 0.12 The result of "upsd" is: Network UPS Tools upsd 2.4.3 listening on 127.0.0.1 port 3493 listening on ::1 port 3493 Connected to UPS [liebert]: usbhid-ups-liebert The complete list obtained with "upsc" is: battery.charge.low: 38 battery.charge.warning: 38 battery.type: PbAc device.mfr: Emerson Network Power device.model: LiebertPSA device.serial: device.type: ups driver.name: usbhid-ups driver.parameter.pollfreq: 30 driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.version: 2.4.3 driver.version.data: Belkin HID 0.12 driver.version.internal: 0.34 ups.mfr: Emerson Network Power ups.model: LiebertPSA ups.productid: 0001 ups.serial: ups.status: OB ups.vendorid: 10af What problem could be there? I would like to paste also a complete tracing of "/lib/nut/usbhid-ups -D -a liebert", but the message would become too big. Please tell me if there is any relevant portion that I could paste here.
