A small step forwards: I am now able to connect to the Overo when it is mounted (I don't think I seated it properly) via /dev/ttyUSB1 at 115200. If I remove the Overo and try the same thing I still don't get a response from the Robovero though.

I have powered up the board that I just received from an external power supply at around 11V. The red LED lights constant until I plug in the USB cable and then the red LED starts blinking as it should. The green LED lights up. All good up till here.

The problem is that under linux there is only a /dev/ttyUSB0 and /dev/ttyUSB1 but there isn't a /dev/ttyACM0. I tried Windows following the tutorial as well and it never asks for the NXP LPC17xx driver. When watching Windows install the drivers one of them is marked failed (see screenshot attached), but in summary here is what I get:

Generic USB Hub  [Ready to use]
USB Composite Device  [Failed]
USB Composite Device  [Ready to use]  
USB Serial Converter A  [Ready to use]
USB Serial Converter B  [Ready to use]
USB Serial Port (COM6)  [Ready to use]
USB Serial Port (COM5)  [Ready to use]

IIRC it initially showed the string "Gumstix Robovero" or similar in the the line that failed before it reverted to "USB Composite Device".

Is this a firmware or a hardware issue? I already have an Overo Water but I cannot connect to it when mounted on the board either and without Wifi I can't go this track either though I am not confident I would get any different kind of results.
