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.

    Do you still have issue while communicating with your modem?
