I'm using this example



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?
