I've attached the lsusb output. [lsusb_output.txt](https://github.com/networkupstools/nut/files/9098853/lsusb_output.txt)

I've tried the same package on a laptop running Debian 11. upsc output is the same. I think even the Eaton Companion shows 00000000 for the serial. That might be...

I've attached both outputs. Sadly it looks to me, that the UPS is simply not giving the information on the input values [eaton-ellipse-eco-650usb.txt](https://github.com/networkupstools/nut/files/9135519/eaton-ellipse-eco-650usb.txt) [lsusb.txt](https://github.com/networkupstools/nut/files/9135521/lsusb.txt) .
