Hi,Defining a host of an HID wired mouse, on an stm32f4 MCU works great.Trying to use a wireless mouse doesn't work at all.The wireless mouse comes in a pair with a keyboard. Pressing a button on the wireless keyboard works well but clicking/moving t...

HI,I'm using an STM32F4 device and CubeIDE SW to interface with a mouse as a host with an HID. I use the USBH_HID_EventCallback function to trigger mouse readings.Can I change the mouse's polling rate so that it will be triggering faster?The current ...

Thanks again guys for your huge help!So at the usbh_hid.c file, there is a section of HID_Handle initiation. On line 197, the systems gets the default polling rate for the device and verifies it is not shorter than the minimum value, as seen below: H...

Thank you guys, for your time and efforts!I will give it a try and update the thread, in case someone else will have the same issue.Thanks

Thanks Jan for the detailed response.So if understand correctly, reducing the HID_Handle->poll value to minimum shall move the HID_Handle->state to HID_GET_DATA earlier.In that case I can modify the HID_MIN_POLL value and keep using the event callbac...

Thanks Pavel,I think you are correct.But per your assumption, the rate with which the FIFO is getting data, is controlled by the mouse, eventually. I will try to implement the manual reading and update the thread.Thanks

Thanks JW,From my understanding, if I use the event callback function, it is the mouse that controls the data rate. I don't mind to request the data in the main program but once I do that (using the Mouse_Info = USBH_HID_GetMouseInfo(phost) function)...
