I am using a adafruit STM32F405 feather, and have written a program for it in the stm32cubeide. I have enabled USB_OTG_FS and also selected VCP under USB_DEVICE under middleware. I sent a simple message using CDC_Transmit_FS() within my main.c file. I wanted to then display the message using minicom but the stm32f405 is not recognized as a virtual com port when i plug it in. Please can anyone help with this problem?
This what i get from dmesg

It appears that there is an error when reading the usb device descripter, any ideas how i can solve this?
HAL_PWREx_EnableUSBVoltageDetector() at end of MX_USB_DEVICE_Init for older Firmware it appears.
I updated from Jan to July release of IDE, MX and STM32CubeF4 releases and my USB_OTG_FS started working (the call above is not present in the latest).
