LibUsbDotNet中的USB通知事件是不是线程安全？

using LibUsbDotNet;
using LibUsbDotNet.DeviceNotify;

class Program
    {
        //USB插拔通知事件
        static IDeviceNotifier DevNotifier;
        static int n = 0;
       
        static void Main(string[] args)
        {
            DevNotifier = DeviceNotifier.OpenDeviceNotifier();
            DevNotifier.Enabled = true;
            DevNotifier.OnDeviceNotify += DevNotifier_OnDeviceNotify;

            while (!Console.KeyAvailable)
                Application.DoEvents();
        }

        private static void DevNotifier_OnDeviceNotify(object sender, DeviceNotifyEventArgs e)
        {
            n++;
            for(int i=0;i <0xffff;i++)
            {
                for (int j = 0; j < n; j++)
                    Console.Write("\t");
                
                Console.WriteLine(i.ToString("X4") + " " + n.ToString());
            }
        }
    }
