Error: Cannot Find the interface for Communication Interface Class

Milad_ · ‎2024-04-09

Hello everyone,

I'm working on controlling my serial modem using the STM32 Nucleo G0B1 board. I've configured the Nucleo as a USB host, and my modem is a CDC-ACM device. I've set up the USB settings in CubeIDE and connected the modem to the Nucleo using a USB cable. I've attached the output of ST-Link for debugging purposes. Everything seems to be working fine until the "HOST CLASS CHECK" stage, where I encountered an error.

Could you please assist me in establishing communication with my modem and resolving this issue?

Thank you for your help.
