I got a more detailed answer from a root session of nut-scanner, and 
fixed ups.conf with it, and restarted nut, but it made little if any diff 
that I can see.

So I did a sudo lsof|grep "nut " -
and got this, more no permissions junk:
gene at coyote:/usr/lib$ lsof |grep "nut "  -
upsd 78510 nut cwd unknown /proc/78510/cwd (readlink: Permission denied)
upsd 78510 nut rtd unknown /proc/78510/root (readlink: Permission denied)
upsd 78510 nut txt unknown /proc/78510/exe (readlink: Permission denied)
upsd 78510 nut NOFD /proc/78510/fd (opendir: Permission denied)
upsmon 78535 nut cwd unknown /proc/78535/cwd (readlink: Permission 
denied)
upsmon 78535 nut rtd unknown /proc/78535/root (readlink: Permission 
denied)
upsmon 78535 nut txt unknown /proc/78535/exe (readlink: Permission 
denied)
upsmon 78535 nut NOFD /proc/78535/fd (opendir: Permission denied)

And I just now used a root session of mc to set both /dev/ttyUSB*
perm to 777. That lt boty heyu and nut strt throwing errors that made 
sense, so I fixed those errors and both are now working with one 
exception, the APC display is saying its due for a fresh battery, but nut 
isn't saying that from a upsc report:

But what happens when I have to reboot in a few days and /dev gets 
repopulated with 0600 devices?

Thanks Manuel.

Take care & stay well

Cheers, Gene Heskett.
