Archdevs, Have there been any changes to startup that would impact the Network UPS Tools startup using the usbhid device? I ask because the nut-server.service that has worked for years, is now failing to come up in the normal boot process. $ upsc phoinix_ups Error: Driver not connected However restarting the service after the system is up and running everything works fine. So it's like there is a new depends for the usbhid driver startup that means it has to wait until something else is now started before it can initialize properly. Any idea what could be causing that or what nut-server.service needs to wait on before it tries to start? After kernel update, the failed log messages are: -- Reboot -- Jan 13 11:06:31 phoinix systemd[1]: Starting Network UPS Tools - power devices information server...
