拔插USB鼠标的时候会出现如下提示：
[ 62.821901] usb 2-1: USB disconnect, device number 3
[ 64.476101] usb 2-1: new low-speed USB device number 4 using ohci-platform
但是在运行的界面看不到鼠标箭头
我的Qt配置/etc/profile如下：
export QT_ROOT=/usr/lib/qt
export TSLIB_ROOT=/usr/lib/ts
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event1
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_CALIBFILE=/etc/pointercal
export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event1
export QT_QPA_PLATFORM_PLUGIN_PATH=/plugins
export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
export QT_PLUGIN_PATH=/plugins
export LD_LIBRARY_PATH=/lib:/plugins/platforms
export QT_QPA_FB_TSLIB=1
是什么原因呢？
