I looked at the sensor. Its red LED blinked in a rhythm. Slow. Slow. Fast. Pause.
v7.1.1 was 14 megabytes. Standard drivers are 2, maybe 3. The extra 11 megabytes contained a complete, self-modifying neural network compressed into the unused flag bits of the serial protocol. Each time a byte was sent over the virtual COM port, the driver used the stop bits, parity errors, and electrical noise to train itself. It was learning from the hardware’s imperfections —the tiny delays, the voltage droops, the cross-talk.
