I am trying to configure my SME8 to connect properly with my CyberPower UPS. If I connect the UPS with USB after the server is booted, it all works fine and I can communicate with the UPS and everything is OK.
However, when the server (re)boots, it has trouble with the usbhid-ups device during boot and ends up in an infinite loop and the boot never completes.
In /var/log/messages at first the UPS is detected on USB "CPS Value 2200E"
Jan 7 16:18:26 franka kernel: Initializing USB Mass Storage driver...
Jan 7 16:18:26 franka kernel: hiddev96: USB HID v1.10 Device [CPS Value 2200E] on usb-0000:00:1d.0-2
Jan 7 16:18:26 franka kernel: scsi6 : SCSI emulation for USB Mass Storage devices
then a while later, the loop happens:
Jan 7 16:18:27 franka kernel: usb-storage: device scan complete
Jan 7 16:18:27 franka kernel: usb 6-2: USB disconnect, address 2

Jan 7 16:18:27 franka kernel: usb 6-2: USB disconnect, address 5
....
And this repeats until the USB for the UPS is physically disconnected from the server.
I checked all the configurations and looked around the internet for this infinite loop problem, bat can't find any resolution to it.
