Mass storage Mass storage demonstration based on the microSD card available on the EVAL boards. Maybe the virtual com port driver cannot buffer the high amount of data they are comeing from the MCU Youll need the ST USB library STM32 USB-Host-Device Lib V2.1.0 and the standard peripheral libraries. I also confirmed that changing the CPU for an STM32 obtained from Farnell on one of these boards fixed the USB issue. VCP USB-to-RS232 bridge to realize a virtual COM port. It also rather looks to me like a large batch of these particular boards with suspect chips is now in circulation, as I have 6 boards obtained in 3 different orders, 2 from UK stock and 4 in 2 lots from China direct (all last couple of months though). I did successfully get the openCM3 CDC example project to work in VSC/Platformio (after sorting out the STlink programming issue discussed in the link) and Macbeth got the USB to work another way, but as it stands the, it looks as though the current STM32duino code and these chips are incompatible. But it only has Win7 and Win8 directories. I downloaded the VCPV1.4.0Setup.exe and ran it. Windows already provide standard (native) drivers for CDC devices Usbser. That is, if windows can find a suitable driver for your device.

I have not found any of the STM32duino code (including bootloaders) to work with these chips, whatever they are. STM Virtual Com Port Driver for Windows 10. After upload, open any serial terminal (like Putty) and find your serial device in Device Manager under Ports (COM & LPT) named USB Serial Device (COMx).
I have tested my boards and the configuration bits at 0圎00FFFC0 are a match for Macbeth's when read using using ST-Link Utility, so the manufacturer as read from the chip is not ST if I understand correctly.
While the discussion is about not being able to program STM32's with STlink, it turns out that the reason it doesn't work is because the CPUID was different than that which would be read from a genuine STM32 part. CDC Device, and CDC Host.For the Host purpose, I will use STM32F411 DISCOVERY Board, and STM32F103 is used as a Device.Both the microcontrollers will be able to communicate with each other using the USB connected between them.

The link below, second page, has more on these boards. In this tutorial I will cover how to implement USB CDC (Communication Device Class) in STM32 using both the modes, i.e.

there may of course be versions of the chip with correct markings, not STM32) that that also don't work. Download and install the STM32 VCP drivers to get Windows to recognize your device. I have concluded that while the boards were sold as STM32F103C8T6 system minimum boards and the chips are labelled as STM32F103C8T6, they are in fact something else with STM32 markings. I was have been having problems getting USB to work with recent STM32F103C8T6 system minimum boards, getting 'device not recognised' messages and 'device descriptor request failed' message in device manager (Win 10).
