    I was frustrated at the constant “new controller detected” everytime i start up the new RetroPie, so i modified the /usr/bin/emulationstation script to check if a controller is found before launching. This is specific to PS3 controllers, but i’m sure you could modify it to handle just about anything.

    Modify the script, removing the $es_bin “$@” at the bottom and add this instead.Essentially it goes into an infinite for loop, checking dmesg. when dmesg shows at least one instance of “input: PLAYSTATION” then it starts the $es_bin “$@”.

    for (( ; ; ))
    do
    if [[ $(dmesg |grep ‘input: PLAYSTATION’ |wc -l) -ne 0 ]]; then
    $es_bin “$@”
    break
    exit 0
    fi
    sleep 1
    done

    So the whole script looks like

    #——
    #!/bin/bash
    es_bin=”/opt/retropie/supplementary/emulationstation/emulationstation”

    nb_lock_files=$(find /tmp -name “.X?-lock” | wc -l)
    if [[ $nb_lock_files -ne 0 ]]; then
    echo “X is running. Please shut down X in order to mitigate problems with loosing keyboard input. For example, logout from LXDE.”
    exit 1
    fi

    for (( ; ; ))
    do
    if [[ $(dmesg |grep ‘input: PLAYSTATION’ |wc -l) -ne 0 ]]; then
    $es_bin “$@”
    break
    exit 0
    fi
    sleep 1
    done
