<p>OpenWRT version 23.05.0-rc3 is, for starters, not supported
anymore by the OpenWRT project, and is old.</p>
<p>The current version is OpenWRT 23.05.05</p>
<p>The reason you are likely getting an old version of NUT when you
load the nut package is because you are using an old version of
openwrt.</p>
<p>Your team needs to sysupdate your 4G LTE Wifi router</p>
<p>You also, in my opinion, need to seriously reconsider running NUT
on an openwrt router. The reason why is that NUT generates
logfiles and writes to the filesystem.</p>
<p>The flash chips that are used on routers are not designed like a
USB flash stick where they are intended to have a read/write
filesystem on them. They have no bad block management with NAND
flash chips. That is provided by a UBI layer. You can read about
that here:</p>
<p><a href="https://openwrt.org/docs/techref/flash.layout">[OpenWrt
Wiki] The OpenWrt Flash Layout</a></p>
<p>SOME of the NAND devices that OpenWRT has been ported to, DO have
complete UBI support, others don't. You did not say what model of
router you are running - but unless you have researched it and are
completely sure that it has a fully functional bad block
management, you can easily cause problems over time attempting to
run programs on an OpenWRT router.</p>
<p>In general it's safest to run READ ONLY programs on openwrt. For
example, the snmpd server. Programs that WRITE to the filesystem
on the OpenWRT router should be avoided.</p>
<p>There's a reason we use hard drives on servers.</p>

you are in the best of health and spirits.</p>

<p class="MsoNormal">For an upcoming UPS Project, our team has
been testing <span style="color:black">
Powercom’s Cleanline T-1500 UPS model whose photo has been
attached with this e-mail. Our team has been testing this
UPS with one of our 4G LTE WiFi router models on which
Network UPS Tools (NUT) Version 2.8.0-3 has been installed.
BUT during the testing our team observed multiple instances
of error message <b><span style="background:yellow">"Data
for UPS [pcmusb] is stale - check driver"</span></b>
being randomly reported by our 4G LTE WiFi router. Here is
the SUMMARY of the issue below for clear understanding
purposes.</span></p>
<p class="MsoNormal"><span style="color:black"> </span></p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoListParagraph" style="margin-left:18.0pt">NUT
Version <span style="color:black">
2.8.0-3 was installed on our 4G LTE WiFi router by our
team.</span></li>
<li class="MsoListParagraph" style="margin-left:18.0pt">Also
our 4G LTE WiFi router had Linux Kernel Version 5.15.127,
OpenWRT Distribution release “23.05.0-rc3” and OpenWRT
Distribution Revision “r23389-5deed175a5” installed on it.
</li>
<li class="MsoListParagraph" style="margin-left:18.0pt"><span
style="color:black">Powercom’s Cleanline T-1500 UPS was
connected with our 4G LTE WiFi router via USB to USB Cable
Connection (</span>i.e. USB Port on router side and USB
Port on UPS side)</li>
</ul>
<p class="MsoListParagraph" style="margin-left:54.0pt">Now when
NUT installed on our 4G LTE WiFi router model unit tried to
poll and fetch values of different UPS parameters from
Powercom’s Cleanline T-1500 UPS model

<p class="MsoListParagraph" style="margin-left:54.0pt">after
both UPS and router had been running for sometime (i.e. for
random period of time):</p>

<li class="MsoListParagraph" style="margin-left:18.0pt">after
that router could not get UPS’s status any more unless we
restart the NUT service</li>
<li class="MsoListParagraph" style="margin-left:18.0pt">and
the router started reporting the error message “Data for
UPS [pcmusb] is stale - check driver” after running for
sometime again</li>

<ul style="margin-top:0cm" type="disc">
<li class="MsoListParagraph" style="margin-left:18.0pt">Our
team tried to increase value of NUT’s timers such as
“pollinterval”, “pollfreq”, “maxage” but still the issue
could not get solved or fixed</li>
<li class="MsoListParagraph" style="margin-left:18.0pt">Kindly
NOTE that our team tested the above with both the NUT
Drivers i.e. blazer_usb and nutdrv_qx. But the same error
message mentioned above was observed.

<li class="MsoListParagraph" style="margin-left:18.0pt">Also
kindly NOTE that our team also tried to test with NUT Driver
“usbhid-ups” but it is seems that this particular Driver is
not supported by

<li class="MsoListParagraph" style="margin-left:18.0pt">Currently
our team is not 100% sure about the exact root cause.</li>

<p class="MsoNormal">Our team need to know the following from
NUT Developers.</p>
<p class="MsoNormal"> </p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoListParagraph" style="margin-left:18.0pt">Which
the is correct NUT Driver that our team need to use on the
4G LTE WiFi router so that it can communicate smoothly and
successfully with
