Bluepill STM32F103C8 Computer not recognizing USB

Hello,

I've been following this http://dangerousprototypes.com/blog/2017/06/21/how-to-stm32f103c8t6-as-an-usb-device-virtual-serial-port-cdc/ tutorial on getting the virtual com port working on my bluepill. I am 100% beyond any shadow of a doubt certain that I have configured everything exactly as the video suggests. I have also followed several other tutorials on the subject, all of which had the same or similar code. However, even given this, I have never even had the computer recognize the USB of the bluepill. I plug the micro-usb end in to the bluepill and the USB end in to my PC, nothing happens. Nothing comes up under device manager, and it can't interact with the bluepill at all.

Any other ideas on what I could be doing wrong? Is there a chance I have a faulty board? The board can still be powered through the micro-usb which is why I don't think my board is faulty.

Any help would be greatly appreciated - thank you.

Are you 100% sure that the MCU on the bluepill is an original STM32 made by ST?

The topic of fake has been discussed very often in this context.
