Here you're referring to just making things work on Windows or macOS, right? I don't think it will be quite as simple with NUT, mostly because the NUT drivers are trying to expose all of the variables and commands, rather than just the simple shutdown bits.<br>
<br>
I'm not sure where a generic HID PDC driver sits in the priority list at the moment, but IIRC the current driver is still fairly tightly coupled to the USB VID and resulting model-specific mappings. So once you get the permissions worked out, you would still need a new source file that maps the HID Usage "paths" to NUT variable names. It's one of those things that in hindsight, it would have been great to fall back to a generic mapping that just looks at the OB and LB bits, but real-world UPSes are messy, and we would have needed those model-specific mappings to be able to distinguish things like input and output voltage.<br>
<br>
That said, if you change the VID/PID to something supported already, things just might work. The "Couldn't retrieve descriptors" is likely a result of the driver dropping root privileges, then not having enough permissions to write to the /dev/bus/usb node to request the HID descriptor. I don't know how your VID/PID got into the udev rules file - VID 2341 doesn't show up in the NUT Git source tree.<br>
