Error IoTimedOut when reading data from the device

Question

I used libUsbDotNet library (C#) to read data from USB device. The program sees the device and turns to it, but gives a response IoTimedOut. The program code is shown below.

    public static UsbDeviceFinder MyUsbFinder = new UsbDeviceFinder(0x10C4, 0xEA61);
    public static UsbDevice MyUsbDevice;

    public static void Main()
    {

        MyUsbDevice = UsbDevice.OpenUsbDevice(MyUsbFinder);
        if (MyUsbDevice == null) throw new Exception("Device Not Found.");

        IUsbDevice wholeUsbDevice = MyUsbDevice as IUsbDevice;
        if (!ReferenceEquals(wholeUsbDevice, null))
        {
            wholeUsbDevice.SetConfiguration(1);
            wholeUsbDevice.ClaimInterface(0);
        }

        UsbEndpointReader reader = MyUsbDevice.OpenEndpointReader(ReadEndpointID.Ep01);

        ErrorCode ec = ErrorCode.None;
        int bytesRead = 0;
        byte[] readBuffer = new byte[32];

        while (true) {

            Thread.Sleep(100);
            ec = reader.Read(readBuffer, 1500, out bytesRead);

            if (bytesRead > 0)
            {
                Console.WriteLine("Data Received");
                // Console.Write(Encoding.Default.GetString(readBuffer, 0, bytesRead));
            }
            else {

                Console.Write("Error type: "); 
                Console.WriteLine(ec);
                Console.ReadKey();

                MyUsbDevice.Close(); 
                break;
            }
        }
    }

I tried to change the reading parameters but it doesn't help. Can you please tell me what it may be related to, it is not clear to me from the libUsbDotNet documentation?
