Hello @Namita​,

You can review the following article that will cover the basic steps to develop an application using the USB Custom HID Class on an STM32 as a Device:

• How to implement a USB device custom HID class on STM32 part1
• How to implement a USB device custom HID class on STM32 part2

Hope this helps you!

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.
