Sounds like a homework problem.

Review the HID Host examples for the specific STM32 you're using, probably a few hundred parts from different families, so you might want to narrow that down a little.

The Cube downloads for assorted families unpack with large example trees, for assorted boards, including HID examples.

Consider using a NUCLEO-F429ZI, the F4 supports HOST operation, and has a HID example..
