<p class="MsoNormal">Dear NUT Developers,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">A very good morning to you and hope that you are in the best of health and spirits.</p>
<p class="MsoNormal"> </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 type="disc" style="margin-top:0cm">
<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>
<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>
<p class="MsoListParagraph" style="margin-left:54.0pt"><span style="font-size:14.0pt; font-family:"Angsana New",serif"> </span></p>
<ul type="disc" style="margin-top:0cm">
<ul type="circle" style="margin-top:0cm">
<li class="MsoListParagraph" style="margin-left:18.0pt">router started reporting the error message
<b><span style="background:yellow">“Data for UPS [pcmusb] is stale - check driver”</span></b></li><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>
</ul>
<p class="MsoNormal"><span style="font-size:14.0pt; font-family:"Angsana New",serif"> </span></p>
<p class="MsoListParagraph" style="margin-left:90.0pt">Note: <strong><span style="font-family:"Calibri",sans-serif">[pcmusb]</span></strong> represents the
<strong><span style="font-family:"Calibri",sans-serif">name or identifier</span></strong> assigned to the UPS instance within the NUT (Network UPS Tools) configuration</p>
<p class="MsoNormal"> </p>
<ul type="disc" style="margin-top:0cm">
<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><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
<span style="color:black">Powercom’s Cleanline T-1500 UPS model whose photo has been attached with this e-mail.
</span></li><li class="MsoListParagraph" style="margin-left:18.0pt">Currently our team is not 100% sure about the exact root cause.</li></ul>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Our team need to know the following from NUT Developers.</p>
<p class="MsoNormal"> </p>
<ul type="disc" style="margin-top:0cm">
<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
<span style="color:black">Powercom’s Cleanline T-1500 UPS model</span> whose photo has been attached with this e-mail?</li><li class="MsoListParagraph" style="margin-left:18.0pt">Which specific parameters within the default Configuration Settings file of NUT Version
<span style="color:black">2.8.0-3</span> on our 4G LTE WiFi router need to be tweaked / changed so that our 4G LTE WiFi router model can communicate with the
<span style="color:black">Powercom’s Cleanline T-1500 UPS model</span> smoothly and successfully?</li><li class="MsoListParagraph" style="margin-left:18.0pt">Which specific parameters within the default ups.conf / upsd.conf file on our 4G LTE WiFi router needs to be tweaked / changed so that our 4G LTE WiFi router model can communicate with the
<span style="color:black">Powercom’s Cleanline T-1500 UPS model</span> smoothly and successfully?</li></ul>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Also I am hereby attaching the Log Files with the Log Messages reported on our 4G LTE WiFi router model. The 1st Log file contains Log Messages during testing with NUT Driver “blazer_usb” while the 2nd Log file contains Log Messages during
testing with NUT Driver “nutdrv_qx”. You will observe the ERROR Message <b><span style="background:yellow">“Data for UPS [pcmusb] is stale - check driver”</span></b> within both these attached Log Files.
