Examples of Custom USB Classes?

I'm trying to code an app that communicates using USB bulk transfers but is simpler than the CDC/VCP and MSC examples in ST's library. I've tried to code a custom USB class, but Windows doesn't like it - it sends me SET_CONFIGURATION(NULL).

Are there any STM32/USB examples that demonstrate how to code custom classes?

Hi

''I've tried to code a custom USB class, but Windows doesn't like it - it sends me SET_CONFIGURATION(NULL).''

That might be because Windows now expect YOU to provide it with a Device Driver for YOUR USB Custom device.
