Ok, I did this, here is how it went (approximately): t=0 power on the UPS, with some load. t=2 min unplug the UPS from mains, alarm goes off. t=33 min low battery alarm goes off. t=35 min ups powers down. As I was doing the test, I added load, to speed up the battery drain, but from the dumps I don't thing that's reported. The win software tells very little about the status of the UPS. This time, I added another capture point, a software running inside the vm (usbsniff), in case for some reason commands sent to the ups where missing. Here are the results (the list would hold large messages): http://www.ariwainer.com.ar/varios/ups/2013-12-21-usbmon-fullcycle.log http://www.ariwainer.com.ar/varios/ups/2013-12-21-usbsniff-fullcycle.log http://www.ariwainer.com.ar/varios/ups/2013-12-21-wireshark-fullcycle.pcapng > Also important are the settings in the UPS monitoring software, such as > timeouts, or behavior options for when the power returns.

Let me know if further tests or more info are needed. Kind regards.
