Further system data or configuration examples:

Data sample
Device connected via USB. It is lacking some data like `ups.load`,
`input/output voltages` and so on (visible on older Smart-UPS 1000 RM
that I'm replacing).

Vendor's PowerChute BE reports those values (screenshots in ticket).

I found some topics suggesting that it may use modbus, not sure if that
is the case here (at least manuals don't mention it, nor it is mentioned
in menus).

NOTE: There seem to be multiple hardware revisions of this model.
There are some with firmware 1.x that are not upgradable, mine is
upgradable to 3.8 (as listed here), some can go up to 7.x series.
So even though they all identify as Smart UPS 750-X, they have
different internal model number. I believe the same apply to 1000W
and 1500W models, as they share the same chassis.

Data sample
Similar to `APC__Smart-UPS_X_750__usbhid-ups__2.7.4__01.dev` - same device
tested with a custom build of NUT, checking if it would help (did not then).

I built HEAD (like previously), run `usbhid-ups -s ups -x port=auto`,
then `upsd` and `upsc` output is as pasted below... Thus nothing new,
except in driver fields.
