Hi there,

I'm using STM32 USB library and I'm working on a project for a HID device. I'm facing some issues with the USBD_HID_SendReport function. I have one endpoint and two input reports. The input reports get sent depending on the events triggered in the system. I populate the buffer to be sent to the host and call the function USBD_HID_SendReport.

For some reason, sometimes the report never makes it to the host. I put the USB sniffer and looks like the report never got sent out. Any ideas why this might be happening.

I'm using

* @version V1.0.1

* @date 31-January-2014

of the USB library.

Best Reards

Hello,

To have more insight into the USB HID using the STM32Cube library, you can review the USB HID example within the

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef0.html

V1.6.0:

STM32Cube_FW_F0_V1.6.0\Projects\STM32072B_EVAL\Applications\USB_Device

I suggest to you using the latest version of firmware package F0 which contains enhancement and bug fixes.

Regards
