David, is this the same system as mentioned in this thread? https://alioth-lists.debian.net/pipermail/nut-upsuser/2020-January/011619.html While wolfy's suggestions are applicable for a serial UPS with an external USB-to-serial adapter, it sounds like your Belkin UPS has the Cypress chip built-in, and the blazer_usb driver expects to talk directly to that chip (bypassing any kernel drivers that create /dev/ttyUSB* nodes). Changing the config file modes from 777 to 640 is likely orthogonal to the problem, but something I'd want to fix sooner than later. What does `ls -l /dev/bus/usb/001/003` show? You can also try starting the driver manually. There are easier ways to do this in newer versions of NUT, but with 2.7.1 and an Ubuntu-like filesystem layout, it would be something like this (assuming the UPS name is still belkinusb in /etc/nut/ups.conf): /lib/nut/blazer_usb -a belkinusb -DD -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
