Agreed. Power up sequencing on dumb low-level interfaces has to be thought through carefully. You may turn on something you don't want to turn on.
I have a device which controls an antique Teletype machine from a USB port. It uses the request to send signal on a USB-simulated serial port to start the Teletype motor. This works fine on Linux. On Windows, the motor starts and stops several times when the USB device is plugged in or Windows starts up. That's because an old Windows feature is probing the serial port for a serial mouse. Annoying.
