Assuming it is a "bluepill" you need to use a usb to ttl converter , the onboard usb doesn't work from the boot loader, it is forĀ  program use if you use the right modules.
The BluePill PCB already has a USB to TTL converter: the CP2102 module, so you do not need another one.

And the microUSB port on the CP2102 should be the ONLY place you plug a microUSB cable in, whether when flashing, or when running OnStep.
