I have two brand new CyberPower UPSs and both of them have connection issues with OMV 4 using the NUT plugin 4.0.13-1. One is a CyberPower CP1500AVRLCD Intelligent LCD UPS System, 1500VA/900W. The other is a CyberPower BRG1500AVRLCD Intelligent LCD UPS System, 1500VA/900W. Both are supposed to be compatible with the usbhid-ups driver. Both have problems communicating over USB to the server (HP Z400). If I stop the UPS service and restart it, it works normally for a while, then loses communication again.
Edit to add: I forgot to add that both of these UPSs communicate fine with a computer running Windows with the CyberPower PowerPanel software!
Typical log messages when I use either of the UPS mentioned above.
Previously, I had a CyberPower CP1000PFCLCD PFC Sinewave UPS System, 1000VA/600W connected to the server using the usbhid-ups driver and never had any communications issues. I've tried changing the USB cable and also the USB port on the server but I still have problems with the two new UPSs.
Any suggestions? Thanks.
