I have a custom arduino board that is basically like any ATMega328P based setup. I'm using the FTDI friend from Adafruit to communicate with it and when the drivers for it are installed you can see in Device Manager (Windows 7 SP1) that the baud rate is set to 9600.
However, in my Arduino sketch, I have the baud rate set to 115200 and I can communicate with it at that speed from a python script.
So, does the setting on the driver properties actually matter?
Main reason I'm trying to figure this out is that this is for a kit that will be sold and I want a setup that will work for anyone with the default driver install. I'm quite happy if it just works by whatever you set in software, but just wanted to be sure that this was the case.
