运行setting 中的校屏程序时 报错为
failed irq                                                                      
unable to get PenDown IRQ 12                                             
QWSTslibMouseHandlerPrivate: ts_open() failed with error: 'Device or resource bu
sy'                                                                             
Please check your tslib installation!
应该是没有关闭触摸屏再次打开,或者是关闭不成功?
试过在ts_open之前运行ts_close,没有效果 
应该怎么关闭呢?
有没有人用过这个程序
