Problem solved.

Hello Dan,
thanks for your reply but this did not work out.

Hello,
Just to update you, I've applied the patch I mentioned but unluckily VBUS still doesn't turn on. This will unluckily take a few more days in order to get to work it seems.
We will update this redmine once we have USB working... Daniel Vincelette
