So you need a HID host, not device. Here is a USB host example for Nucleo L4:

https://github.com/STMicroelectronics/STM32CubeL4/tree/master/Projects/NUCLEO-L4R5ZI/Applications/USB_Host/HID_Standalone

You can also get it from the CubeL4 package installed on your machine by CubeIDE or CubeMX.

You will need to port this example to Nucleo STM32L496ZG.
