The UPS remains on until the batteries completely drain and it has to turn off to protect itself.<o:p></o:p></p><p class=MsoNormal>Apart from that, reporting, messaging, shutdown process etc all works well.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>On shutdown I can see <o:p></o:p></p><p class=MsoNormal>instcmd: command [shutdown.stop] handled<o:p></o:p></p><p class=MsoNormal>instcmd: command [shutdown.return] handled<o:p></o:p></p><p class=MsoNormal>Shutting down in 30 seconds<o:p></o:p></p><p class=MsoNormal> Waiting for UPS to cut power.<o:p></o:p></p><p class=MsoNormal>Will now halt.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The PC turns off put UPS stays running until batteries run out.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So I can see that the driver issues the command and thinks that it is “handled”. Looking at it with higher debug level I can see that the driver reports a “USB no ACK” to these instcmds. Checking the USB with wireshark shows that this text string originated in the UPS, ie it is a text string returned in response to the instcmds.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Looking closer at the USB descriptor it presents MEC0003 rather than the MEC0002 that I see all over the fora.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So it would appear that there is a new variety of MEC protocol. <o:p></o:p></p><p class=MsoNormal>Has anyone else seen this?<o:p></o:p></p><p class=MsoNormal>Is there any work ongoing with this MEC0003 protocol?<o:p></o:p></p><p class=MsoNormal>What can I do to help this cause? (bear in mind I’m a Linux newbie – but with good backup <span style='font-family:Wingdings'>J</span> )<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Le meas,<o:p></o:p></p><p class=MsoNormal>John<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div><br clear="both">
