Does anyone have an example of USB-HID implementation with both IN and OUT endpoints ?

[Coconop]

The USB-HID ST library comes with an example of Mouse device that I have adapted successfully.

However it only has a single Input endpoint to send reports to the Host.

I am mainly interested in OUT endpoint for communication Host to device.

Does anyone have already coded something similar ?

For example a mouse/Keyboard with LEDs feedback or Joystick with vibration feedback.

I cannot find any concrete example on the web...

This library has proper HID class implementation:

https://github.com/IntergatedCircuits/USBDevice

Set the USBD_HID_OUT_SUPPORT to 1 in usbd_config.h to enable OUT endpoint support. When implementing the interface, you have to call USBD_HID_ReportOut() every time you want to receive data from the host. The SetReport callback will provide the received data.

I planned to do so, I was just waiting to check in details the code and also some potential other answers.

Sorry it is my 1st "contribution" to this community.
