I am having a problem with the Turn off UPS after shutdown setting with a usbhid-ups driver in standalone mode. I have tested running upscmd ups load.off.delay 20 in the web terminal and that works so I know the USB shutdown command works it is just not being run on shutdown. It looks like at shutdown it is unmounting the folders before the shutdown command can be run.
Unmounting local file systems:
...
/usr: successfully unmounted
...
Restarting udev to be able to shut the UPS inverter off...
/etc/rc.d/rc.nut: line 277: /etc/rc.d/rc.udev: No such file or directory
Shutting down UPS driver...
/etc/rc.d/rc.nut: line 240: /usr/sbin/upsdrvctl: No such file or directory
reboot: Power down
