Technically you need to apply for a PID and VID for your device but most people seem to just make them up! The ST micro has no VID/PID, you program that as part of the device descriptors.

I found the easiest way was to use the STM32 FS Device lib and WinUSB. That avoids writing a driver and gets good performance. the is good documentation for WinUSB called something like WinUSB How To. Start with one of the basic examples in the USB library projects folder most similar to what you want to do.
