ARDUINO USB HOST CONTROLLER

Hi, I am trying to work with usb host controller but when I connect usb host cshield to arduino uno the IDE shows that it cannot upload the sketch. I dont know what is the reason for that. I am attaching an image which shows the connection. Let me know if I am doing anything wrong.

Thank You.

I am attaching an image which shows the connection.

To what? The bathroom wall? I'm not going there.

Disconnect the shield before uploading code to the Arduino, if you have it connected to the hardware serial pins.
