Is there a correct procedure to install em7455 drivers for the port correctly on a branded device without Linux? I can make this work with Linux if I run a script, but I’d like to be able to do it all within windows and hopefully be able to automate the process. I downloaded the generic drivers and tried installing via command line with the USBCOMP=8 argument, but it still makes it so I have to manually select the 3 com ports. Is there a way to avoid having to manually choose these 3 com port drivers?

Thanks!
