Hi @KMin .1​,

Your project is successfully worked for me (using STM32CubeMX 6.7 and STM32Cube_FW_F4_V1.27.1)

Please make sure to follow this article USB device not recognized, with the solution is to either increase the heap size or configure the USB library to use static allocation.

Check if the USB_OTG_FS_DP and USB_OTG_FS_DM wires are swapped.

Check if you have this driver installed properly!

Hope my answer helps you.

Most likely CubeMX just didn't configure that setting properly or at all. That is an absolutely normal thing for that broken bloatware generator.
