“We are trying to develop a USB Host HID application where using the controller STM32F4, and the USB stack library available on the ST website, we are trying to send data/command to an USB HID device. But in the library we downloaded from ST site, the host HID application has examples for mouse and keyboard application only.In case of Mouse and keyboard, Host receives but does not transmit back anything while in our application we need to also transmit data.
So do you have any particular HID host example codes or guideline documents for STM32F4xx controller which demonstrates how to interface external USB device TOUCHPAD MOUSE(GP415U-5321) using the ST USB library? “,
