The keymap may be hard coded. I suspect that to be the case, as the picture of
the device shows letters printed on it.
They could also send data back to the keyboard. The data flow is bidirectional.
There are a number of configurable registers in a keyboard that go beyond the
simple LEDs (typematic delay, typematic repeat rate, etc) You can just send
random data down the line. Enough of the protocol is defined that you could
detect between a stock keyboard and a custom keyboard.
Or you could just do the remapping in software on the host.
