I have been Working on Creating USB device mode for STM32 NUCLEO-L4P5ZG ,but the device(other than ST link) is not showing connected in device manager. Is it required to install any driver for the PC in order to recognize the device?

What kind/class of device?

Have you connected the other USB cable to the board (bottom edge)?

The device is Mouse. yes, I have connected the bottom edge.

presently I'm configuring the OTG mode ,in that host mode is working but for device mode it is not showing the connected device in the USB port manager

You're going to get another device for the PC. A USB bus analyzer.
