I am making a academic project "Data transfer between two usb flash drives using microcontroller without using PC". For this project I need USB host controller and Usb peripheral controller.It is very hard and not compatible to use cypress IC which is generally used for this USB file transfer project. Any suggestion regarding this project , whether it's about IC or any other idea,,, anything regarding this project would be highly appreciated. Plz mail me at jigneshdetroja@gmail.com . I would be highly grateful for ur effort.
