Arduino Due with Ubuntu 14.04 in VirtualBox

Hi all,

Recently I've been trying to interface my Arduino with ROS and while experimenting I was having serial disconnection issues with the Due but not with my Uno.

I am trying to connect my Arduino to Ubuntu by passing the port in Virtual Box rather than as just a USB device because when I connect it as a USB device I have problems programming the Due (I didn't experience this problem with the UNO strangely enough).

When I program the Due with it interfaced as a USB device, it stops midway through programming most of the time and is only able to complete some of the time. The times that it does complete, it would still disconnect while running ROS and communicating over serial. This did not occur with the Uno.

I followed this guide to setup everything:

And the same solution was given in this thread:

Attached are pictures of how I setup my port, added myself into dialout and vboxfm and the error.

Thanks for any help you can offer.

I suspect VirtualBox problems are little beyond the scope of the Arduino Forum.
