Key strokes from keyboard connected to Nucleo-F767ZI are not recognized in HID_standalone application example

I have a setup as required by the HID_standalone example program. When I am starting the program the keyboard that is connected to CN13 is properly recognized (last two sentences on the screen are:

KeyBoard device found! and

HID class started

When I then start HID, the program tells me to enter characters via that connected keyboard. Iam doing that without any response.

What is wrong?

Rgds.,

when trying to do that test with the controller's tech example (https://controllerstech.com/stm32-usb-host-hid/) the " USBH_HID_EventCallback" is never entered, when a key of the USB keyboard is pressed.

I have done that test with three different keyboards.
