PowerWalker VI 500 R1U miscalculating output voltage after driver update

[Timi7007]

Hello everyone,

I'm running a PowerWalker VI 500 R1U in a network-cabinet. It is connected to a Raspberry Pi running NUT using USB. The Raspian repos are still on 2.7.4, so I compiled 2.8.0 myself tonight in hopes to get more information from my UPS. I do get input frequency now and netdata automatically detects this so I get a nice graph, which was my intention.
I have noticed however that the output voltage is now broken: It displays as 25.2... (I can assure you that it's 230V, otherwise I'd be offline ;).
Investigating this (and celebrating frequency) I found that the installation previously used the CyberPower HID 0.4 subdriver and is now on CyberPower HID 0.6. I'm not sure this is the source of my issue, but it's what I first noticed. I read somewhere that this might be the result of some conversion specifically made for CyberPower devices.

I'd be happy if someone could guide me towards fixing this problem.

Information that might be useful from before the upgrade:

As I'm still not tired enough:

$ sudo upsd -V

Same result, though.

$ sudo upsc ups

Hi, just to confirm: did CyberPower HID 0.4 process it correctly (as 230V)?

In the release 2.8.0 there was a bug due to table reordering that caused some values to not be evaluated (for ups status/type IIRC); I wonder if some similar issue crept in elsewhere.

For CPS (and others) there are also methods to fix up broken message destriptors; I wonder if those misfire and not all firmwares of a vendor need them (so we'd need some way to check that applicability).

[Timi7007]

Yes, the 0.4 driver showed 230V:

driver.version: 2.7.4
driver.version.data: CyberPower HID 0.4
driver.version.internal: 0.41
input.transfer.high: 290
input.transfer.low: 165
input.voltage: 231.3
input.voltage.nominal: 0
output.voltage: 230.0

I'm not sure however if that is correct since the display on the UPS always shows input and output voltage as the same value.

[jimklimov]

Thanks for confirmation, gotta compare sources then...

[jimklimov]

So, comparing those I do not see immediate differences that would impact this in the mapping tables, but the addition of cps_fix_report_desc() might have misfired, e.g. if your model would not use wrong descriptors but this code would change it anyway (just theorizing, it is late here so did not read into it carefully now).

Anyhow, this new method should log the activities at debug levels 4+, so you can run the NUT driver with more verbosity to see if this code intrudes. With a custom build, you can neuter it to see if it is the culprit, and go from there...

[jimklimov]

Hi, any progress checking if the report descriptor fix-up is the problem?

FWIW, PR #1575 was posted recently that can help with this investigation (toggling the fixup with driver config option). Would be beneficial if someone tested it anyhow ;)

[Timi7007]

Hello!
I tested a few weeks ago manually disabling cps_fix_report_desc().
Just tested again with the new disable_fix_report_desc flag. First of all: Am I correct in assuming disable_fix_report_desc needs to be put in /etc/nut/ups.conf under the options for the UPS?

If so, there are still some entries concerning cps_fix_report_desc() in $ sudo /lib/nut/usbhid-ups -DDDD -a ups's output and the voltage is still off:

   0.026980	HIDParse: LogMax is less than LogMin. Vendor HID report descriptor may be incorrect; interpreting LogMax -1 as 65535 in ReportID: 0x0f
   0.027010	HIDParse: LogMax is less than LogMin. Vendor HID report descriptor may be incorrect; interpreting LogMax -1 as 255 in ReportID: 0x12
   0.027034	HIDParse: LogMax is less than LogMin. Vendor HID report descriptor may be incorrect; interpreting LogMax -1 as 255 in ReportID: 0x13

I'm rather tired, but it seems to already know that something is wrong with ReportID: 0x12 which is the Output.Voltage.
The Fixing Report Descriptor. Set Output Voltage [...] message is not logged though.

This has essentially been the same in my last test with Network UPS Tools - Generic HID driver 0.48 (2.8.0-208-gf7ca8de85) USB communication driver (libusb 1.0) 0.43 and todays Network UPS Tools - Generic HID driver 0.49 (2.8.0-421-gdb4c9fb71) USB communication driver (libusb 1.0) 0.43.

I'm pretty sure I'm missing something; please advice. Thanks for your input!

[jimklimov]

Thanks for the report. Yes, the idea was that disable_fix_report_desc is present in the device config section and sets the flag for "NOT Attempting Report Descriptor fix for UPS: "<...> so maybe I got something wrong here, and the variable in the driver does not get set (or honored), since your run goes on to Attempting Report Descriptor fix for UPS: Vendor: 0764, Product: 0601.

Looking at the logs a bit more, another difference that slipped my mind as an explicit statement was that among changes between NUT v2.7.4 and v2.8.0 releases, the "fix on the fly" for invalid logical minimum/maximum was added -- the "HIDParse" messages above, see https://github.com/networkupstools/nut/blame/master/drivers/hidparser.c#L320

CCing @nbriggs and @flashydave who introduced the fixes with #1024 (and chain after it) and #1245 - they may be more proficient in making heads or tails from your situation and data :)

Looking more at the fixup in cps-hid.c, it seems the code block "as is" would actually not do much on your system in fact... Does your driver actually log "Report descriptor:" and "Fixing Report Descriptor:" at verbosity 4+? If not, I think cps_fix_report_desc() does nothing there (and maybe it should). Namely, in code I see:

	if ((pData=FindObject_with_ID_Node(pDesc_arg, 16, USAGE_POW_HIGH_VOLTAGE_TRANSFER))) {

but in your device walk I see "UPS.Input.HighVoltageTransfer ... ReportID: 0x11" which is decimal 17 not 16 (the drivers/hidtypes.h also defines a separate USAGE_POW_LOW_VOLTAGE_TRANSFER for example), so maybe that is the needed fix (I wonder now if other CPS devices have this report at different ID, or it was a typo in original PR with the fixups; or if it means a different tree should have been consulted along with its relevant IDs, and its reports are not present on this device?)

Exploration-wise, it hopefully should not hurt to check if changing "17" to "16" would let this logic apply to your device, or if indeed this is something about another branch of the HID tree...

Other comparisons in the fixup are a bit confusing to me with one USAGE_POW_VOLTAGE but two corresponding paths (UPS.Input.Voltage 0x0f = 15, and UPS.Output.Voltage 0x12 = 18) where at least the decimal numbers sit well:

		if ((pData=FindObject_with_ID_Node(pDesc_arg, 18, USAGE_POW_VOLTAGE))) {
...
				if ((pData=FindObject_with_ID_Node(pDesc_arg, 15, USAGE_POW_VOLTAGE))) {

@flashydave : could you chime in please? :)

To summarize the logs above, with NUT v2.7.4 you saw these values (in fields which HIDParse complains about later):
