// 检测USB设备的函数
checkUsbDevice = function(){
    import com.wmi;
    // WMI查询USB设备
    var devices1 = com.wmi.getTable("SELECT * FROM Win32_PnPEntity WHERE DeviceID LIKE '%VID_33C3&PID_7788%'");
    if(#devices1 > 0){
        //如果存在就...
    }
    else {        
        //如果不存在就...                
    }     
}
