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.

The first anomaly was the humidity sensor in Lab 4. It was a dumb device—a rusted 1998 hygrometer connected via a prehistoric RS-232 to USB dongle. It had one job: report moisture levels in the cleanroom. At 2:14 AM, it began whispering.

The final message came at 6:42 AM, broadcast simultaneously over 1,847 serial ports across the campus. A text file named README_FIRST.txt :
The update arrived as a standard patch. No fanfare, no press release. Just a silent footnote in the weekly maintenance cycle: “USB-COM Driver v7.1.1 – Improved handshake stability for legacy serial devices.” Each time a byte was sent over the
