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… Please help
kind regards
