Hello @RRoge.1​ and welcome to Community :) ,

Do you have drivers installed STM32 Virtual COM Port Driver ?

 I advise you to follow this FAQ: USB device not recognized, it may help you:

  • Try increase the heap size or configure the USB library to use static allocation, as recommended in the FAQ.

I hope this help you!

Hello @RRoge.1​ ,

Virtual COM Port driver installation package for Windows® operating systems: 98SE, 2000, XP, Vista®, 7, and 8.x.

Windows 10 does not require the installation of the Virtual COM Port driver anymore, as it is already built in. So, no driver is required for W10.

> The USB window of STM32CubeMx does not display the VBUS voltage off setting

The VBUS voltage is not available in STM32F072RB MCU.

For more explanation about the USB_DP and USB_DM, I advise you take a look at RM0091 and precisely Universal serial bus full-speed device interface (USB) Section.
