STM32072B-EVAL + STM32Cube: unmodified USB VCP example not recognised properly

I'm using this example

STM32Cube_FW_F0_V1.7.0\Projects\STM32072B_EVAL\Applications\USB_Device\CDC_Standalone

 

Which should simply present a VCP in Windows/Linux, after the drivers are installed (for Windows): 

STSW-STM32102 - STM32 Virtual COM Port Driver - STMicroelectronics - STMicroelectronics 

 

For the setup, I do the following

- "For power supply from USB (CN4) to STM32072B-EVAL only, JP19 is set.." - from UM1714 User Manual

- link TX / RX for loop-back using jumpers (but not important I just want the device to be recognised for now)

- connect a standard USB cable from CN4 USB port to my computer. The cable is fine, as I also use this one connected to CN13 for programming via ST-Link.

I get this unhappy message

 

 

I checked to see if what recognised by Ubuntu / Linux. It is not

 

Am I missing something?
