Tim,

It's possible that these changes didn't make it in. I admit that would be my 
knee-jerk reaction to seeing an older version number, but the last occurrence 
of "PSA" in the drivers/ Git log is 2009.

Derek,

Do you have a link to the message where the problem was solved?

Not sure what you mean by "Latching power fail" - setting FSD through upsd?

It's hard to tell without seeing the results of upsc for the combination of 
your UPS and NUT version, but if you have a valid battery charge level, you can 
use the "ignorelb" setting to synthesize a low battery notification.
