The firmware reads the digital inputs and the quadrature signals from the rotary encoders, debounces everything, and presents itself to the host as a standard USB HID gamepad. This means the cabinet works with any operating system without custom drivers.
Stream implementations can and do ignore backpressure; and some spec-defined features explicitly break backpressure. tee(), for instance, creates two branches from a single stream. If one branch reads faster than the other, data accumulates in an internal buffer with no limit. A fast consumer can cause unbounded memory growth while the slow consumer catches up — and there's no way to configure this or opt out beyond canceling the slower branch.
