Kernel messages and `lsusb -v` just give the same name for [i]Product as 
is reported for MODEL by `apcaccess`...

Newer models are all -SMT and they required going into UPS control panel 
and enabling Modbus.

Now I seem to recall that the newest 3000VA models, when connected via 
USB, may have flip-flopped in a similar or the same way that you 
describe. We had to get the proper APC/Schneider accessory serial cables 
to make them work with apscupsd.
