I also confirmed that changing the CPU for an STM32 obtained from Farnell on one of these boards fixed the USB issue.

ST-LINK, ST-LINK/V2, ST-LINK/V2-1, STLINK-V3 USB driver signed for Windows7, Windows8, Windows10.
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). STMicroelectronics and 3rd party partners provide a range of STM32 utilities most of the time to ease developers’ life when used with specific embedded software solutions. It emulates fakes a usb removable flash drive with a fat16 file system to provide info when reading files and to write a new application to flash if the file is properly formatted using the uf2 tool. 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.

Is Motorola first defined on its MC68HCXX series processor.

I have not found any of the STM32duino code (including bootloaders) to work with these chips, whatever they are. SPI is the abbreviation of English Peripheral interface Serial, as the name suggests is the serial peripheral interface. 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. The link below, second page, has more on these boards.
there may of course be versions of the chip with correct markings, not STM32) that that also don't work. 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).
