Hello! I struggle with a peculiar device that "just works" under Linux - my ETA 1600-sinus UPS. I've tried hacking it directly and via "NUT" UPS software - but no luck. On Linux it's enough to set blazer_usb driver in upsc.conf and software connects normally to the device (using Megatec protocol). Under FreeBSD I experience crazy issues with a similar setup - after a whole day of hacking, I start to guess it's about libusb provided with FreeBSD 13.0 on arm64 (one I've been using). I explained some technical details here: https://github.com/networkupstools/nut/issues/1077 If anyone has a glimpse of an idea what I may also try to get it working=E2=80=A6 Please help kind regards --=20 Daniel Dettlaff Versatile Knowledge Systems verknowsys.com
