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.

The shield on the photos doesn’t look like an original Arduino USB Host Shield. So please provide links to the schematics of the shield you’re using.
