how to set serial baud rate on NUCLEO-F091RC from default 9600 to something else?
I'm using Hello World example on: https://developer.mbed.org/components/X-NUCLEO-IKS01A1/
The default serial rate is 9600. I've searched source code and cannot find where this is set. Code uses printf() and I believe it defaults to stdio.

Instead of using the default stdio, you should explicitly use the PC USB serial port. That allows you to modify the baudrate.
#include "mbed.h"
Serial pc(USBTX, USBRX); // tx, rx
int main() {
pc.baud(9600);
pc.printf("Hello World!\n");
}

you can use baud.. but write it after main()
ex : Serial pc(USBTX, USBRX);
int main() { pc.baud(57600); ... }
