Hello,

In HAL USB_Device class library function (usbd_customhid.c) USBD_CUSTOM_HID_Setup() not exist case CUSTOM_HID_REQ_GET_REPORT(bug or not?), but in usb spec  GET_REPORT must be realized. 

Could you recommend right steps for working with CustomHID USB device class?

And may be exist appnote for it?

Hi panov.roman,

CUSTOM_HID_REQ_GET_REPORT is not implemented by ST. 

So, we would suggest ST adding this function and include it into usbd_customhid.c

Hello Mayla, the custom HID example from CubeMX USB middleware is NOT enumerating to Windows (which just complains about the device descriptor request failed), as you can see in attached picture.  I am wondering if this might be due to the ill-formed CUSTOM_HID_ReportDesc_FS.  From what I read in USB Complete, 4th Edition, the 2 bytes (the last byte being ''end collection'') you have as a descriptor is ill-formed.  Please find my steps to get to this point in my
