Ok, trying to make sense of the capture (again: it's all guessing, I have no experience with usb protocol): Up until packet #255/131 seconds in the pcap file, the payload is 0x03, then it changes to 0x01 , and then it changes again to 0x02 at packet #3975/2081 seconds. It seems like: 0x01 = AC failed 0x02 = Battery low. 0x03 = AC is ok It looks simillar to the UPS implementation example from http://www.usb.org/developers/devclass_docs/pdcv10.pdf _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
