AM335X GP EVM usb鼠标问题

请教各位前辈，我在板子上插上USB鼠标，能识别到设备

但是光标没有反应，我在这个帖子http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/15332.aspx

看到说是修改matrix-gui-2.0这个文件，

    if [ -e /dev/input/touchscreen0 ]                                 
    then                                                  
        export QWS_MOUSE_PROTO=Tslib:/dev/input/touchscreen0
    fi

我把touchscreen0换成mouse0，光标没有出现，请问应该怎么修改呢？让它同时支持触摸屏和USB鼠标

Jian Zhou：

默认情况下，鼠标插上就可以工作的

可是插上鼠标后光标没反应啊
