NUT package (2.8.0 and below)

tnowak

Hi!
Last year I was struggling to connect to Ever ECO Pro 1200 AVR CDS UPS.
This was mostly because nut was in version 2.7 and support for that UPS has been added in 2.8.

Lately I tried it again. This time nut package is already in version 2.8 (2.8.0_2).
I've installed it and configured with usbhid driver and some basic extra arguments:

port=auto
vendorid=2e51
productid=0000

Unfortunately, it still doesn't work. Why?

Log:

Feb 22 20:42:29	upsmon	71579	Poll UPS [ever] failed - Driver not connected

@tnowak First, I would recommend removing everything from the extra arguments section. Following that, test again. If it doesn't work please post the output from usbhid-ups, either from the system log or from the command line. The command line would be this:

/usr/local/libexec/nut/usbhid-ups -a ever

FYI, the port=auto is handled by the package and should never be added to the extra arguments section for usbhid. The vendorid/productid can be added back later if necessary.

@dennypage Solved it by adding user=root in ups.conf section. But this is rather a workaround than a solution. Anyway, this seems to be a problem of nut / file / dev permissions.

I expect that you are actually in the same situation as the new gen APC listed above: No quirk covering your UPS device (I actually don't see anything from Ever in the table at all).

To confirm, use these steps:

disable nut (Services / UPS / Settings) and save the config
unplug the usb connection to the ups and wait 5 seconds
re-plug the usb connection to the ups
run "usbconfig -d ugen0.2 show_ifdrv"

and post the result. My expectation is that you will see two lines, similar to this:

ugen0.2: <American Power Conversion Smart-UPS1000 FW:UPS 16.0 / ID1047> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (10mA)
ugen0.2.0: uhid0: <American Power Conversion Smart-UPS1000 FW:UPS 16.0 / ID1047, class 0/0, rev 2.00/0.01, addr 1>

Hi @dennypage - thanks again for all your help looking into the signal 10/11 issue with CyberPower UPS units. I'm fine to continue running mine with the interruptonly flag workaround for now even if fewer variables are monitored. After a couple days of running this way, things appear to be stable. If it this setup ends up crashing at some point, I'll probably give the updated usbhid-ups driver a try. Also, if you do end up releasing a nut-devel package at some point that includes fixes post 2.8.0, I'd be happy to try that out as well.

@dennypage You are amazing I appreciate all you do. Again, thanks for taking the time to look into this issue reported within this discussion. It seems to be a problem with many other users now and you already have a solid solution for it.

ugen0.2.0: uhid0: <EVER ECO PRO AVR CDS, class 0/0, rev 2.00/1.00, addr 2>

PS. I've also noticed a problem with nut loosing connection to this UPS even with user=root after some time. Then when I restart nut it shows up again.

Yep, that shows a kernel driver attached to the device. Same situation as the new series APC devices. Not too surprising, because I don't find any Ever devices defined in the usb table.

You can either use the user=root approach, or you can develop a quirk setting for /boot/loader.conf.local. Based on your prior post, I believe that the correct value would be this:

hw.usb.quirk.0="0x2e51 0x0002 0x0000 0xffff UQ_HID_IGNORE"

You can test this in advance by running this:

usbconfig add_dev_quirk_vplh 0x2e51 0x0002 0x0000 0xffff UQ_HID_IGNORE

followed by unplugging and replugging the usb cable to your ups. If the values are correct, when you run "usbconfig -d ugen0.2 show_ifdrv" again, you should only see one line of output like so:

ugen0.2: <EVER ECO PRO AVR CDS> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

The ugen0.2.0 should be gone.

If this test works then you can add the line to your /boot/loader.conf.local file.

As to loosing communication after a time, I would still need to see the output from usbhid-ups, either from the system log or from the command line. There seem to be a few issues that do not produce entries in the system log, so I would recommend using the command line as previously discussed.

Thanks, this was very helpfull. I had to modifiy command a bit, as I've noticed its add_dev_quirk_vplh not vlph and I changed pid (product id) to 0x0000. Now the second line is gone:

Now NUT starts without user=root just fine:

Sorry, typo. I corrected the original post.

But soon after one minute or so:
Feb 23 22:28:08 kernel pid 21611 (usbhid-ups), jid 0, uid 66: exited on signal 10

Congratulations, you are a double winner.
The post above regarding the CyberPower UPS units applies to you as well.

Wow, amazing! I deployed that workaround for the time being and it works reliably now! Looking forward for future nut package releases that solves this issue.

You're the man @dennypage! Thank you VERY much for your support that is extremely competent and helpful.

@dennypage

the "usbhid-ups" binary built from the FreeBSD nut-devel port you provided earlier this week to test looks to have solved the problem for me (or at least for those that have CyberPower UPSs). As of this morning eastern time, it's been running for over 72 hours with no more "exit on signal 10" errors in my system log file. Thanks for all your help in identifying the issue and that its already been fixed in the newer version of nut.

JonathanLee

@shaffergr is this available form package manager now?

shaffergr

@jonathanlee

No. Denny provided me a build from nut-devel branch so that we could validate if the signal 10 issue was fix or not.

@dennypage I've been seeing logs like this:

Feb 25 19:37:13 gatekeeper kernel: pid 29800 (usbhid-ups), jid 0, uid 0: exited on signal 10

Feb 25 19:37:35 gatekeeper upsmon[28298]: Poll UPS [tripplite] failed - Driver not connected

<goes on the same until manually restarted.>

setting interruptonly appears to have mitigated it. UPS is a Tripp Lite SMART1500LCD rack mount unit. It seemed to work fine prior to the last update.

dennypage

@jpp-0 I sent you the dev build of usbhid-ups. Please let me know if it works for you.

JPP 0

@dennypage Thanks sending the dev version, it looks to be working, it's been running for over 8 hours with all the extra config (interruptonly and user=root etc) removed. No crashes. It correctly detected power loss and power restored. If it fails laster I'll post and update but I'm not expecting it to as it would fine within minutes before.

@dennypage can confirm interruptonly does the job as a workaround with my Cyberpower UPS. Many thanks.
