STM32F407 USB Device Not Recognized as Virtual COM Port (VCP)

[Sanyam_07]

Hello everyone,

I’m working on a project where I am using STM32F407 and I’m trying to establish USB communication between my STM32F407 Discovery board and a PC. I have configured the board for USB_OTG_FS in STM32CubeMX, and I’m trying to use it as a Virtual COM Port (VCP). However, when I connect the board to the PC using the USB_FS port, it’s not being recognized as a COM port or any device at all in the Device Manager.

I want to read the output of the ADC channels using the hercules software 

I would really appreciate any suggestions or guidance on:

1. Getting the board to show up as a VCP in the Device Manager.
2. Troubleshooting USB enumeration issues.

Hi @Sanyam_07 

I didn't catch your thread from here.

Ensure you're using a USB cable that supports data transfer, not just charging. Some cables only provide power without data capabilities.
