If the UPS really only uses the RX and TX pins, the setting of  
'cablepower' is irrelevant.

Have you also tried *all* the other subdrivers? The 'phoenix'  
subdriver was an early attempt to work around some issue we found in a  
particular USB to serial converter, which later turned out to be  
better solved in the 'ippon' subdriver. Make sure you have also tested  
the latter.

We do. I'll commit the changes to the development version once we've  
ironed out the last things here.
