I want to implement USB-CDC device on STM32F070P6. I've generated the needed code using STM32CubeMX but it doesn't seems to work.
I can't see USBD_CDC_Init to be called, thus when the device is flashed I get this error:
[15798.097292] usb 2-7: device descriptor read/64, error -71

Am I missing something?
