Did that.  Manual startup of the driver now works without -u root,
indicating (I think) that the udev rools are doing their job.  This

However, starting with upsdrvctrl still reports driver startup failing

(I plan to submit a patch for the installation instructions  if we
can figure this out, so your advice will benefit the next person to
trip over this, too.)
