Using CubeMX for STM32F411: USB Device code not functional

I have a STM32F411 Discovery board, when I use the latest CubeMX to generate templates that configure the board as a USB device audio class, the board doesn't get recognized by the host computer (as in, the computer doesn't think there is a USB device plugged in at all, not even USBlyzer captures any communication on the USB bus.)

The USB descriptor in the code should make the board show up as a loudspeaker in the computer, which is the case when I tried the same thing on a STM32F407 Discovery board.

Could anyone confirm this? Or help me with a workaround?
