In Moravia's instructions of cable use, it makes an exception with a serial number range including your unit:

QUOTE:

The cable does NOT work on previous HP calculators (HP15c LE, HP12c
prior to 2015, and a new version with batch code “C1GP000”
, HP20b, HP30b), even if they have the same POGO connector. These other models
follow a serial RS232 protocol, have different functions assigned to each pin
and different voltage levels. It also cannot be converted to be used with these
calculators because it is missing the IC that handles the voltage levels and the
protocol. Operating this cable with HP15c LE, HP12c prior to 2015, HP20b
or HP30b may destroy the calculator!

That´s something interesting!!
So I´ll have to open it to check if the PCB has the place for the USB connector...
