Unknown USB Device
Some users may see an "Unknown USB Device (Device Descriptor Request Failed)" in
Windows Device Manager. This is a common occurrence in Windows. The issue occurs
because there is no corresponding device firmware or driver available for the USB port
connecting to ST stm32f microcontroller (CN25). The device needs to be developed
further by user or by project basis, otherwise the device is not supported on Windows.
