Hi !

Looks like example based on old code. With new CubeMX and SDK , USB API is different. I have created minimal DISCO429 mx/keil project for investigation of the problem. ( test_vcp.zip In attachment ) Is any known reason exist why new export from Cube not work out of box ? Best regards !

Old and Working, keep that in mind as you labour forward.

Don't know, It's new and poorly validated? I've got no plans to use Cube right now, the people I work with prioritize ''working'' over ''new and shiny''.
