Posted on June 11, 2015 at 17:57it seems strange to me that for a microcontroller like this there are not examples or tutorials to explain how to use properly the usb.
People have made careers out of understanding how to write Windows device drivers, applications and create USB peripherals. I think ST makes a business out of selling to companies with engineers that have these skill sets, rather than create every possible use case for their parts. It seems strange to me that people can't work with technical documentation directly without a video or a complete worked example.
If you step back from Cube, where you press a button and code pops out the bottom, ST has release several USB libraries, with a selection of examples for host and device configurations. The STM32F4-DISCO board represents a small subset of the capabilities, some of the examples will target the EVAL series boards, so will need porting/tailoring to other hardware.
ST also has FAE's, you should push in via your distributor to see what resources they can provide.
