请教各位前辈，我在板子上插上USB鼠标，能识别到设备

[ 962.674512] hid-generic 0003:04CA:0061.0002: input: USB HID v1.11 Mouse [PixArt USB Optical Mouse] on usb-musb0
但是光标没有反应，我在这个帖子www.deyisupport.com/.../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
