Hi all, In light of issue #2666 ( https://github.com/networkupstools/nut/issues/2666#issue-2623441838), I "sniffed" USB traffic from APC's `PowerChute Serial Shutdown` software (with the help of this guide (https://www.youtube.com/watch?v=0MC-D_oNzbk)). I hope to be able to find out the shutdown command for my APC "Back-UPS BX750MI FW:295202G -302202G". APC's `PowerChute Serial Shutdown` software is able to shut the UPS down, so there must be a command, is my reasoning.
*Any help on figuring this command out from the pcap files, is welcome!* I haven't got the slightest idea on how to go about it... I was able to generate two logs. The scenario was both initially the same: I unplugged the UPS from the electricity grid, and the `PowerChute Serial Shutdown` software started closing down my (Windows) laptop. Then I tried two scenarios: - `2024-11-14-APC-BX750MI-1.pcap`: I let everything run its course, and the UPS shut down, a little over a minute after my laptop had shut down completely (so maybe two minutes after initiating the process, as referenced on that forum I linked somewhere above?). I then plugged the UPS back in, and it restarted (of course). - `2024-11-14-APC-BX750MI-2.pcap`: As soon as Windows notified me of the shutdown that was going to occur, I plugged the UPS back in. I was pleasantly surprised that the same process as in scenario 1 happened, and the UPS power cycled. The only caveat is of course that I don't know whether the `PowerChute Serial Shutdown` software shut down `USBPcap` prior to giving its final command - the holy grail - to the UPS... I don't think this is the case: I saw `2024-11-14-APC-BX750MI-2.pcap` "growing" even after I plugged the UPS back in. (Uploading files to a mail link is probably useless, so here's a link to a directory on my Google Drive, where they can be found: https://drive.google.com/drive/folders/12xLZH4YWJGXEjNETs2YBJix4boIUVDAE?usp=sharing .) Thanks in advance to any and all! ;) Kind regards, Erik
