APC UPS Modbus support. Can't get it going.

[Plutoaurus]

Have tried a few times to get NUT installed with usb modbus support and haven't been successful.

I last tried following this: https://github.com/networkupstools/nut/wiki/APC-UPS-with-Modbus-protocol

I always end up frustrated when it endlessly fails with missing dependencies not in any guide and going back to the beginning to the first line and wondering why 14 years later it's still so difficult. This is a bit of a rant and cry for help sorry.

Stephane in the libmodbus original repo is active and still updating, what's holding this back and can we do anything to help push the commit through?

The NUT repo seems to have 2 releases with modbus support but not for usb. Is this planned at all?
