USB and L4 discovery board

Thanks for the feedback ‘Diabolo38’. I followed your advice and build a CDC usb project using STMCube.
Was actually straight forward, less complicated than I thought. Some minor Macro error in the stmCube build code but easy to solve and everything builds. Thats the good part.

Runtime is actually still no success. I do not get any USB interrupts when plugging it into a host.
One thing I noticed os that the USB led in active without having it hooked up to the host.

I have the feeling it might be something hardware related. Anybody ever done sucessfully USB on a L469 discovery board?

Unfortunately the pins for USB are not available on the outside connector. Maybe a trace could shed some more light on the issue.
